Re: PgSQL vs Ms.Access slow in search - Mailing list pgsql-odbc

    I fooled myself for a while by accidently turning tracing on in the
ODBC driver manager (under the tracing tab). This slowed everything down
while I was trying to work out why my new shiney view was so sloooowwwwwww
:). Also check the commlog driver option is unchecked.
    If you find a query doing the same find but in a where condition (eg
SELECT * FROM tbl WHERE col=1234) then it might be the additional reading
its doing to set up all the other data seen on the grid. Try starting the
postmaster with -d2 to see if that gives usefull info on the queries being
executed.
