Hm. Run the postmaster with -d2 so that queries are logged into
the postmaster log file, and see what query the client is really
sending. I'll bet it's not what you think it is.
Another possibility is that there's some horrid inefficiency
in transmitting the query results, but unless this query is
returning a whole lot of data, that doesn't seem like it'd
explain 90 seconds.
