Add postgres_fdw contrib module. There's still a lot of room for improvement, but it basically works, and we need this to be present before we can do anything much with the writable-foreign-tables patch. So let's commit it and get on with testing. Shigeru Hanada, reviewed by KaiGai Kohei and Tom Lane

# contrib/postgres_fdw/Makefile
MODULE_big = postgres_fdw
Split all OBJS style lines in makefiles into one-line-per-entry style. When maintaining or merging patches, one of the most common sources for conflicts are the list of objects in makefiles. Especially when the split across lines has been changed on both sides, which is somewhat common due to attempting to stay below 80 columns, those conflicts are unnecessarily laborious to resolve. By splitting, and alphabetically sorting, OBJS style lines into one object per line, conflicts should be less frequent, and easier to resolve when they still occur.

Add file version information to most installed Windows binaries. Prominent binaries already had this metadata. A handful of minor binaries, such as pg_regress.exe, still lack it; efforts to eliminate such exceptions are welcome. Michael Paquier, reviewed by MauMau.

PG_CPPFLAGS = -I$(libpq_srcdir)
Prevent accidental linking of system-supplied copies of libpq.so etc. We were being careless in some places about the order of -L switches in link command lines, such that -L switches referring to external directories could come before those referring to directories within the build tree. This made it possible to accidentally link a system-supplied library, for example /usr/lib/libpq.so, in place of the one built in the build tree. Hilarity ensued, the more so the older the system-supplied library is. To fix, break LDFLAGS into two parts, a sub-variable LDFLAGS_INTERNAL and the main LDFLAGS variable, both of which are "recursively expanded" so that they can be incrementally adjusted by different makefiles. Establish a policy that -L switches for directories in the build tree must always be added to LDFLAGS_INTERNAL, while -L switches for external directories must always be added to LDFLAGS. This is sufficient to ensure a safe search order. For simplicity, we typically also put -l switches for the respective libraries into those same variables. (Traditional make usage would have us put -l switches into LIBS, but cleaning that up is a project for another day, as there's no clear need for it.) This turns out to also require separating SHLIB_LINK into two variables, SHLIB_LINK and SHLIB_LINK_INTERNAL, with a similar rule about which switches go into which variable. And likewise for PG_LIBS. Although this change might appear to affect external users of pgxs.mk, I think it doesn't; they shouldn't have any need to touch the _INTERNAL variables. In passing, tweak src/common/Makefile so that the value of CPPFLAGS recorded in pg_config lacks "-DFRONTEND" and the recorded value of LDFLAGS lacks "-L../../../src/common". Both of those things are mistakes, apparently introduced during prior code rearrangements, as old versions of pg_config don't print them. In general we don't want anything that's specific to the src/common subdirectory to appear in those outputs. This is certainly a bug fix, but in view of the lack of field complaints, I'm unsure whether it's worth the risk of back-patching. In any case it seems wise to see what the buildfarm makes of it first. Discussion: https://postgr.es/m/25214.1522604295@sss.pgh.pa.us

postgres_fdw: Add "used_in_xact" column to postgres_fdw_get_connections(). This commit extends the postgres_fdw_get_connections() function to include a new used_in_xact column, indicating whether each connection is used in the current transaction. This addition is particularly useful for the upcoming feature that will check if connections are closed. By using those information, users can verify if postgres_fdw connections used in a transaction remain open. If any connection is closed, the transaction cannot be committed successfully. In this case users can roll back it immediately without waiting for transaction end. The SQL API for postgres_fdw_get_connections() is updated by this commit and may change in the future. To handle compatibility with older SQL declarations, an API versioning system is introduced, allowing the function to behave differently based on the API version.

postgres_fdw: Split out the query_cancel test to its own file This allows us to skip it in Cygwin, where it's reportedly flaky because of platform bugs or something. Backpatch to 17, where the test was introduced by commit 2466d6654f85.

REGRESS = postgres_fdw query_cancel
Fix EvalPlanQual handling of foreign/custom joins in ExecScanFetch. If inside an EPQ recheck, ExecScanFetch would run the recheck method function for foreign/custom joins even if they aren't descendant nodes in the EPQ recheck plan tree, which is problematic at least in the foreign-join case, because such a foreign join isn't guaranteed to have an alternative local-join plan required for running the recheck method function; in the postgres_fdw case this could lead to a segmentation fault or an assert failure in an assert-enabled build when running the recheck method function. Even if inside an EPQ recheck, any scan nodes that aren't descendant ones in the EPQ recheck plan tree should be normally processed by using the access method function; fix by modifying ExecScanFetch so that if inside an EPQ recheck, it runs the recheck method function for foreign/custom joins that are descendant nodes in the EPQ recheck plan tree as before and runs the access method function for foreign/custom joins that aren't. This fix also adds to postgres_fdw an isolation test for an EPQ recheck that caused issues stated above. Oversight in commit 385f337c9.

postgres_fdw: SCRAM authentication pass-through This enables SCRAM authentication for postgres_fdw when connecting to a foreign server without having to store a plain-text password on user mapping options. This is done by saving the SCRAM ClientKey and ServeryKey from the client authentication and using those instead of the plain-text password for the server-side SCRAM exchange. The new foreign-server or user-mapping option "use_scram_passthrough" enables this.

Fix SHLIB_PREREQS use in contrib, allowing PGXS builds dblink and postgres_fdw use SHLIB_PREREQS = submake-libpq to build libpq first. This doesn't work in a PGXS build, because there is no libpq to build. So just omit setting SHLIB_PREREQS in this case. Note that PGXS users can still use SHLIB_PREREQS (although it is not documented). The problem here is only that contrib modules can be built in-tree or using PGXS, and the prerequisite is only applicable in the former case. Commit 6697aa2bc25c83b88d6165340348a31328c35de6 previously attempted to address this by creating a somewhat fake submake-libpq target in Makefile.global. That was not the right fix, and it was also done in a nonportable way, so revert that.
