Thread:
Hi,
I'm having this message when trying to perform
a query.. someone knows what do I have to do to
fix it?
Thanks
pqReadData() -- backend closed the channel unexpectedly.
This probably means the backend terminated abnormally
before or while processing the request.
We have lost the connection to the backend, so further processing is
impossible. Terminating.
Have an excellent day

You are tickling a bug. That message means the backend crashed while executing your query. Right off hand I would sugguest testing the same query with 7.0RC1 from ftp.postgresql.org to see if the error still exists in the about-to-be newest release. Hope that helps, Mike Mascari

Terminating. What is the query? What version of pgsql? What does your server log say? Regards, Ed Loehr
Hi, The query is simple: select count(*) from table; I have the same error message with almost all queries, I'm trying to debug what's new on that table (data) because it was working fine.. The version I'm using: PostgreSQL 6.5.3 on i586-pc-linux-gnu, compiled by gcc egcs-2.91.66 The table: +----------------------------+----------------------------+------+ | Field | Type |Length| +----------------------------+----------------------------+------+ | dfoclave | int4 not null | 4 | | dfoforo | int4 not null | 4 | | dfopadre | int4 | 4 | | dfonombre | varchar() | 80 | | dfotitulo | varchar() | 80 | | dfofecha | timestamp not null | 4 | | dfotexto | text | var | +----------------------------+----------------------------+------+ On Tue, 25 Apr 2000 15:20:55 -0400, Mike Mascari wrote: > Please post the query, the definition of the tables the query is > accessing and the version of PostgreSQL you are using.

Unless the table is unusually large, I don't see how the backend could die on this one. Perhaps you could peform a manual COPY, drop and recreate the table and its indexes and COPY the data back in. Hope that helps, Mike Mascari
I had this same problem after a user had cntrl^Z quit from psql several times in the middle of queries. He then performed a vacuum which locked it up further. After I removed the lock file I could not perform even the simplest queries. The only way I fixed it was to drop the db and restore it from a previous pd_dump. > From: "Teruel Tony" <teruel_tony@excite.com> > Date: Tue, 25 Apr 2000 13:53:42 -0700 (PDT) > To: pgsql-general@postgresql.org > Subject: Re: [GENERAL] > > Hi, > > The query is simple: > > select count(*) from table; > > I have the same error message with almost all queries, > I'm trying to debug what's new on that table (data) > because it was working fine.. > > The version I'm using: > > PostgreSQL 6.5.3 on i586-pc-linux-gnu, compiled by gcc egcs-2.91.66 > > The table: > > > +----------------------------+----------------------------+------+ > | Field | Type |Length| > +----------------------------+----------------------------+------+ > | dfoclave | int4 not null | 4 | > | dfoforo | int4 not null | 4 | > | dfopadre | int4 | 4 | > | dfonombre | varchar() | 80 | > | dfotitulo | varchar() | 80 | > | dfofecha | timestamp not null | 4 | > | dfotexto | text | var | > +----------------------------+----------------------------+------+ > > On Tue, 25 Apr 2000 15:20:55 -0400, Mike Mascari wrote: >> Please post the query, the definition of the tables the query is >> accessing and the version of PostgreSQL you are using.
