Here's a v4 that is actually more or less feature-complete:
it removes no-longer-needed complexity such as PG_TRY blocks.
I've checked that Valgrind shows no leaks in the postgres_fdw
and dblink tests after applying this on top of my other
patch series.
0001 is like the previous version except that I took out some
inessential simplifications to get to the minimum possible
patch. Then 0002 does all the simplifications. Removal of
PG_TRY blocks implies reindenting a lot of code, but I made
that a separate patch 0003 for ease of review. (0003 would
be a candidate for adding to .git-blame-ignore-revs, perhaps.)
0004 is the old 0002 (still unmodified) and then 0005 cleans
up one remaining leakage observed by Valgrind.
regards, tom lane
