You might post the results of "EXPLAIN ANALYZE <your SQL here>;" ...
be sure to run it in a transaction if you want to be able roll it
back. Perhaps try "EXPLAIN <your SQL>;" first as it is faster, but
EXPLAIN ANALYZE shows what the planner is doing.
Is there any way I can gather some information by tracing the query
that's currently actually running?
strace doesn't help much, but is there anything else I can do?
As far as I know, the only tools that exist are
pg_stat_activity, top, and iotop
Have I missed one?
Thanks,
Richard
