The next step would be to turn on PostgreSQL's statement logging and
statement duration. Issue the queries from VFP and then check what
statement that PG is actually getting. If the statement that PG is
getting looks good, try executing that statement prefixed with explain
analyze from the psql command line to help identify where the
performance problem is.
