Overall, I'm really getting the feeling that this procedure was optimized for
Oracle and/or MSSQL and is hitting some things that aren't such a good idea
for PostgreSQL. I highly suggest that you try using log_duration and
log_statement (and in 7.4 log_min_duration_statement) to try to locate which
particular statements are taking the longest.
