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

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 function to list cached connections to foreign servers. This commit adds function postgres_fdw_get_connections() to return the foreign server names of all the open connections that postgres_fdw established from the local session to the foreign servers. This function also returns whether each connection is valid or not. This function is useful when checking all the open foreign server connections. If we found some connection to drop, from the result of function, probably we can explicitly close them by the function that upcoming commit will add. This commit bumps the version of postgres_fdw to 1.1 since it adds new function.

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.
