Hello!
As pg_stat_activity.current_query truncates statements to about 255
characters, I've tinkered a bit with gdb, as suggested by Tom Lane a
little while ago. But when I attach to the backend in question, the only
output I get from p debug_query_string is some number, for example:
mysrv:/var/log # gdb /opt/pgsql/bin/postgres 1485

What am I doing wrong?
Kind regards
