for input/ and output/ directories, because with the addition of
largeobject_1.source, they're not the same list. Apparently the current
buildfarm process does not exercise whether 'make distclean' leaves a
clean tree behind, else the farm would have been failing for awhile.
now complete). Update for the MSVC6/Borland support now being only libpq.
Move most of the information about full MSVC build from README file into

module and teach PREPARE and protocol-level prepared statements to use it.
In service of this, rearrange utility-statement processing so that parse
analysis does not assume table schemas can't change before execution for
utility statements (necessary because we don't attempt to re-acquire locks
for utility statements when reusing a stored plan). This requires some
refactoring of the ProcessUtility API, but it ends up cleaner anyway,
for instance we can get rid of the QueryContext global.
Still to do: fix up SPI and related code to use the plan cache; I'm tempted to
try to make SQL functions use it too. Also, there are at least some aspects
of system state that we want to ensure remain the same during a replan as in
the original processing; search_path certainly ought to behave that way for
instance, and perhaps there are others.
even if none of the fields in the pg_class row change. This behavior is
necessary to ensure other backends flush rd_targblock values that might
point to truncated-away pages. We got this right pre-8.2 but it was broken
by overoptimistic change to not write out the pg_class row if unchanged.
Per report from Pavan Deolasee.
fix it. Add macroses DatumGetNDBOX, PG_GETARG_NDBOX and PG_RETURN_NDBOX.
Backpatch for 8.2 too.
Previous versions use version 0 calling conventions. And fmgr code detoast
values for user-defined functions.
check_sql_fn_retval allows binary-compatibility cases, the expression
extracted from an inline-able SQL function might have a type that is only
binary-compatible with the declared function result type. To avoid possibly
changing the semantics of the expression, we should insert a RelabelType node
in such cases. This has only been shown to have bad consequences in recent
8.1 and up releases, but I suspect there may be failure cases in the older
branches too, so patch it all the way back. Per bug #3116 from Greg Mullane.
Along the way, fix an omission in eval_const_expressions_mutator: it failed
to copy the relabelformat field when processing a RelabelType. No known
observable failures from this, but it definitely isn't intended behavior.
fixup various places in the tree that were clearing a StringInfo by hand.
Making this function a part of the API simplifies client code slightly,
and avoids needlessly peeking inside the StringInfo interface.
log_min_messages does; and arrange to suppress the duplicative output
that would otherwise result from log_statement and log_duration messages.

this, add a 16-bit "flags" field to page headers by stealing some bits from
pd_tli. We use one flag bit as a hint to indicate whether there are any
unused line pointers; the remaining 15 are available for future use.
This is a cut-down form of an idea proposed by Hiroki Kataoka in July 2005.
At the time it was rejected because the original patch increased the size of
page headers and it wasn't clear that the benefit outweighed the distributed
cost. The flag-bit approach gets most of the benefit without requiring an
increase in the page header size.

their regression tests with VARSIZE/SET_VARSIZE defined to reverse byte order.
