Hi,

I've just upgraded two servers to 8.0.0, using PGDG RPMs.

One of them is working well; however I'm experiencing problems in the 
other one.

I first thought that this was a VACUMM issue; but then I saw that I can't 
execute any command.

First case: Connected to template1 using psql and ran VACUMM. Here is the 
log output (debug 5) (same thing happens when I run vacuumdb from the 
command line)

=============================================================================

<postgrestemplate1%tVACUUM>STATEMENT:  VACUUM ;
=============================================================================

Now, second case:

template1=# \c proftpd
You are now connected to database "proftpd".
proftpd=# SELECT passwd FROM users WHERE userid='istanbul';
ERROR:  canceling query due to user request

And the log shows:

=============================================================================

<postgresproftpd%tidle>STATEMENT:  SELECT passwd FROM users WHERE 
userid='istanbul';
<postgresproftpd%tidle>DEBUG:  StartTransaction

<postgresproftpd%tidle>LOG:  statement: SELECT passwd FROM users WHERE

<postgresproftpd%tidle>STATEMENT:  SELECT passwd FROM users WHERE

<postgresproftpd%tSELECT>ERROR:  canceling query due to user request

userid='istanbul';
<postgresproftpd%tidle>DEBUG:  proc_exit(0)
<postgresproftpd%tidle>DEBUG:  shmem_exit(0)
=============================================================================

What might be the problem? The upgrade process was done as usual...
