QueryBuffer 20K exceeded - still...

Hi!
I'm still dealing with "QueryBuffer exceeded, core dump..".

I've tried using
psql -e < xx.sql
psql -f xx.sql

as Bob Dusek suggested...

or inside psql with \i xx.sql.

I've broken the sql script in two... after a few lines of the second part,
the same error... should I download again and recompile , or others have
the same problem ?

I've scanned the mailing lists, and this problem seems to have happened
before - although no clear solution !

What should I do ?

System Configuration
--------------------
Operating System : linux 2.0.36 (elf) Redhat 5.0+5.2 recompiled kernel

PostgreSQL version : 6.4.1(corrected;=6.4.2)<-maybe the problem is here?

Compiler used : gcc 2.7.2.3

Hardware:
---------
P133;64RAM;3G
Linux pluto 2.0.36 #1 Tue Oct 13 22:17:11 EDT 1998 i586 unknown

rpm -q glibc:
glibc-2.0.7-29

Versions of other tools:
------------------------
GNU Make version 3.76.1
flex version 2.5.4

After many inserts... I've got this message:

query buffer max length of 20000 exceeded
query line ignored

and then, a few inserts later, because the scritp went on...
PQsendQuery() -- query is too long. Maximum length is 8191
query buffer max length of 20000 exceeded
query line ignored
Segmentation fault (core dumped)

Thank you in advance!
