Tom Lane	5ef26b8de3	Use LOAD not actual code execution to pull in plpython library. Commit `866566a690` is insufficient to prevent dump/reload failures when using transform modules in a database with both plpython2 and plpython3 installed. The reason is that the transform extension scripts use DO blocks as a mechanism to pull in the libpython library before creating the transform function. It's necessary to preload the library because the dynamic loader won't do it for us on every platform, leading to "unresolved symbol" failures when the transform library is loaded. But it's not necessary to execute Python code, and doing so will provoke a multiple-Pythons-are-loaded error even after the preceding commit. To fix, use LOAD instead of a DO block. That requires superuser privilege, but creation of a C function does anyway. It also embeds knowledge of the underlying library name for each PL language; but that's wired into the initdb-time contents of pg_pltemplate too, so that doesn't seem like a large problem either. Note that CREATE TRANSFORM as such doesn't call the language module at all. Per a report from Paul Jones. Back-patch to 9.5 where transform modules were introduced.	10 years ago
Tom Lane	8805af0886	Sort $(wildcard) output where needed for reproducible build output. The order of inclusion of .o files makes a difference in linker output; not a functional difference, but still a bitwise difference, which annoys some packagers who would like reproducible builds.

Andrew Dunstan	d27fad73e8	Enable transforms modules to build and test on Cygwin. This still doesn't work correctly with Python 3, but I am committing this so we can get Cygwin buildfarm members building with Python 2.	11 years ago
Noah Misch	525a6a0d45	AIX: Link TRANSFORM modules with their dependencies. The result closely resembles linking of these modules for the "win32" port. Augment the $(exports_file) header so the file is also usable as an import file. Unfortunately, relocating an AIX installation will now require adding $(pkglibdir) to LD_LIBRARY_PATH. Back-patch to 9.5, where the modules were introduced.	11 years ago
Noah Misch	21a101848b	MinGW: Link ltree_plpython with plpython. The MSVC build system already did this, and building against Python 3 requires it. Back-patch to 9.5, where the module was introduced.	11 years ago
Tom Lane	91e79260f6	Remove no-longer-required function declarations. Remove a bunch of "extern Datum foo(PG_FUNCTION_ARGS);" declarations that are no longer needed now that PG_FUNCTION_INFO_V1(foo) provides that. Some of these were evidently missed in commit `e7128e8dbb`, but others were cargo-culted in in code added since then. Possibly that can be blamed in part on the fact that we'd not fixed relevant documentation examples, which I've now done.	11 years ago

Tom Lane	b14cf229f4	Use += not = to set makefile variables after including base makefiles. The previous coding in hstore_plpython and ltree_plpython wiped out any values set by the base makefiles. This at least had the effect of running the tests in "regression" not "contrib_regression" as expected. These being pretty new modules, there might be other bad effects we'd not noticed yet.	11 years ago
Andrew Dunstan	f802c6ddba	Enable transforms modules to build and run with Mingw builds. These modules were all missing essential Windows scaffolding, including resources files and descriptions, and links to the relevant library import files. This latter item means that the modules can't be built with pgxs on Windows, as we don't install the import files. If we ever decide to install them this restriction could probably be removed. Also, as with plperl we need to make sure that perl's CORE directory is last on the include list, as on Windows it appears to contain some headers with names that clash with names of some headers we include.	11 years ago
Peter Eisentraut	cac7658205	Add transforms feature This provides a mechanism for specifying conversions between SQL data types and procedural languages. As examples, there are transforms for hstore and ltree for PL/Perl and PL/Python. reviews by Pavel Stěhule and Andres Freund	11 years ago
