Try a make clean and then recompiling PL/Java with -g option, i.e.
make PGSQLDIR=<...> CFLAGS=-g
or, if you care to debug the binary:
make PGSQLDIR=<...> CPPFLAGS=-DPLJAVA_DEBUG=1 CFLAGS=-g
The result of the latter compilation will be a binary that goes into a
loop the first time PL/Java is initialized. It prints out the pid of the
process and asks you to attach a gdb. So you do:
gdb /usr/local/pgsql/bin/postgres <the pid>
Then, inside of gdb you set the breakpoints you need and then issue:
set pljavaDebug=0
continue
this breaks the loop. Hope this helps,
Regards
