Hello all,

  Just so this problem is logged in the system, I am making an overly vague
bug report.  I have no nice method of repeating this as it requires a large
database with somewhat broken RI to run for a long time before running VACUUM
FULL ANALYZE;
I get:

dropsites=# vacuum full  analyze;
WARNING:  Rel pg_type: TID 12/46: InsertTransactionInProgress 27217603 - can't
shrink relation
WARNING:  Rel pg_type: TID 12/47: InsertTransactionInProgress 27217603 - can't
shrink relation
WARNING:  Rel pg_attribute: TID 152/1: InsertTransactionInProgress 27217603 -
can't shrink relation
WARNING:  Rel pg_attribute: TID 152/2: InsertTransactionInProgress 27217603 -
can't shrink relation
...
...
And so on.  The source code says "this should never happen".
This took place on the following system:
dropsites=# select version();
                               version
---------------------------------------------------------------------
 PostgreSQL 7.3.2 on i386-unknown-freebsd4.6, compiled by GCC 2.95.4
(1 row)

[dropsites@m sendpage]$ uname -a
FreeBSD ***.****.com 4.9-PRERELEASE FreeBSD 4.9-PRERELEASE #0: Wed Sep 17
11:18:42 PDT 2003     ***@****.com:/usr/obj/usr/src/sys/WAY2EASY  i386

Any more details you may request and I shall do my best to deliver.  I am
currently trying to get this to happen on -STABLE, but to no avail.
Thanks all.

7.4 has downgraded those messages to NOTICEs, and says

                    /*
                     * This should not happen, since we hold exclusive
                     * lock on the relation; shouldn't we raise an error?
                     * (Actually, it can happen in system catalogs, since
                     * we tend to release write lock before commit there.)
                     */

If you saw it on anything besides a system catalog, then I'm interested,
but otherwise not to worry.

BTW, you really should update to 7.3.4.
