Hi All,
I get this error when I try to connect a web application running on 
tomcat, to a postgreesql database.....
Below is the data from tomcat logs--
---
com.rapidigm.bacs.db.BacsDBException: (executing StatementCallback): 
encountered
SQLException [ERROR: No parser with id 17555]; nested exception is 
java.sql.SQL
Exception: ERROR: No parser with id 17555
----

And the next one is from postgresql logs....
$ /usr/local/pgsql/bin/pg_ctl -D /usr/local/pgsql/data start
postmaster starting
[postgres(at)myMachinename ~]$ LOG:  database system was shut down at
