Oh, if only life were so simple. Consider two modules mod1 (source files mod1a.c and mod1b.c) and mod2 (source files mod2a.c and mod2b.c). mod1a.c: contains sql-callable function foo() which calls an extern function bar() defined in mod1b.c. mod1a.o and mod1b.o are linked to make mod1.so. mod2a.c: contains sql-callable function baz() which calls an extern function bar() defined in mod2b.c. These are linked to make mod2.so. Guess what happens when foo() and baz() are both called from within the same backend.... (Perhaps we should be linking contrib and pgxs modules with -Bsymbolic on those platforms where it matters?) -- Andrew. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
