Error log fillingup - Mailing list pgsql-general

Hi All

I'm running postgreSQL 7.3 on 2 installations, both with the same problem.

The error logs for both installations are filling up with the following;

ESTERROR: 42703: column "options" does not exist
ESTLOCATION: transformColumnRef, parse_expr.c: 396
ESTSTATEMENT: select @@options

This has become a real nuisance.
I have not defined a table 'options' and non of the tables I have defined have a column called 'options'.
I am not aware of this call being made, but it is filling up the error logs at an alarming rate.

All connections to the databases are through unixODBC.

I hope someone can shine some light on this problem.  It would have to be affecting the performance of the DB.
The DB's have been running for a few years and appear to be stable.  Just this error reoccurring.
My concern is that it could mask a real error when it happens.

Many thanks
