yeah! it's using the one that ships with 8.4.0
postgres@casanova1:~/pg_releases/pgtests$ ldd test-libpq [...other no related libraries...]libpq.so.5 =>
/opt/PostgreSQL/8.4/lib/libpq.so.5(0x00007f7ef6db2000)
The only way i can compile with the patched version of libpq is with this
gcc -o test-libpq test-libpq.o -L../pgsql/src/port -lpgport
-L../pgsql/src/interfaces/libpq -lpq -L../pgsql/src/port
-Wl,--as-needed -Wl,-rpath,'/usr/local/pgsql/head/lib' -lpgport
BTW, i can compile with the unpatched version if i add -lpgport (seems
like this patch is adding a dependency)
gcc -o test-libpq test-libpq.o -L/usr/local/pgsql/head/lib -lpq -lpgport
