Hi, Because there was no response for this question already posted in pgsql-j...@postgresql.org mailing list, I'm posting it here.
I'm using PostgreSQL 8.2 and my production server is based on CentOS release 5.2 (Final). JDBC Jar: postgresql-8.2-508.jdbc4.jar I noticed from my server log that some INSERT statements are failing with "invalid message format" PSQLException. Once this exception is thrown, it is not committed to the database. What could be the reason for this? EXCEPTION org.postgresql.util.PSQLException: ERROR: invalid message format STACKTRACE org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse(QueryExecutorI mpl.java:1592) org.postgresql.core.v3.QueryExecutorImpl.processResults(QueryExecutorImpl.ja va:1327) org.postgresql.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.java:193) org.postgresql.jdbc2.AbstractJdbc2Statement.execute(AbstractJdbc2Statement.j ava:452) org.postgresql.jdbc2.AbstractJdbc2Statement.executeWithFlags(AbstractJdbc2St atement.java:337) org.postgresql.jdbc2.AbstractJdbc2Statement.executeUpdate(AbstractJdbc2State ment.java:283) I also read about this on: http://archives.postgresql.org/pgsql-jdbc/2008-04/msg00085.php "JDBC driver is doing something wrong when calculating a message length or message content for the frontend/backend protocol" But how do I resolve this issue? http://archives.postgresql.org/pgsql-jdbc/2004-03/msg00142.php you can't represent a \0 byte in a text/varchar constant Even though I don't have much idea on encoding, I have a little doubt on whether encoding is a problem. Here is my database encoding: mydb=# \l List of databases Name | Owner | Encoding ----------------------+----------+----------- mydb | zoniac | SQL_ASCII Any pointers in right direction are appreciated. -- Sent via pgsql-sql mailing list (pgsql-sql@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql
