While debugging with valgrind, I always receive the following error
message.



==30439== Invalid free() / delete / delete[]

I compiled a program with -L/usr/local/pgsql/lib -lpq

and then ran it with valgrind to check for memory leaks.

unfortunately, I don't know enough about pg to really understand what
could be casuing this, but problems like this can easily lead to
infrequent segfaults =).

Josh.
