Sorry for the late answer, I was on halydays.

The calls to libpq are from the C source, then the TCOB_LD_LIBRARY_PATH 
doesn't act on it. This only acts for finding the routines found on tdba.c

My recomentation is, first link tdba.c with libpq. This can be done 
easily because shared libs can be linked with other shared libs. This 
should reduce the time needed to find libpq.  Then the problem is the 
time to fund the libraries found on tdb02a. A good solution is to rename 
the shared object to something like libtdba.so.

If this doesn't work try to inser displays and printf on the cobol and c 
source and see where is the time spend exactly.

If nothing helps, ask me again with more detailed info.
