I am using libpq to access a PostgreSQL 8.2.7 database.

I am encountering segfault errors when the query length exceeds some 
value greater than 633 characters and less than 2492 characters. The 
database log shows the message
LOG:  08P01: unexpected EOF on client connection

The query that causes problems through libpq can be run directly in psql 
without a problem.

Is there a limit on the length of a query, and is there a way around this?

thanks,

Charles Seaton

Almost certainly, this is a bug within the code calling libpq, and not
in libpq itself.  Many people routinely use queries much longer than
that ...
