You could enable logging of plans and timings using some GUC
variables:
<http://www.postgresql.org/docs/8.1/static/runtime-config-statistics.html>
<http://www.postgresql.org/docs/8.1/static/runtime-config-logging.html#RUNTIME-CONFIG-LOGGING-WHAT>
The output is different from explain's, but most of the information
should be there.
