8.3.0: vacuum full analyze: "invalid memory alloc request size"

[Tomas Szepe <szepe(at)pinerecords(dot)com>]

Hello,

Trying to run "vacuum full analyze" on a ~200MB UTF8 database fails with:

fs=> vacuum full analyze;
WARNING:  skipping "pg_authid" --- only table or database owner can vacuum it
WARNING:  skipping "pg_database" --- only table or database owner can vacuum it
WARNING:  skipping "pg_shdepend" --- only table or database owner can vacuum it
WARNING:  skipping "pg_shdescription" --- only table or database owner can vacuum it
WARNING:  skipping "pg_auth_members" --- only table or database owner can vacuum it
ERROR:  invalid memory alloc request size 4294965504

But not always, sometimes it goes through w/o a problem:

fs=> vacuum full analyze;
WARNING:  skipping "pg_authid" --- only table or database owner can vacuum it
WARNING:  skipping "pg_database" --- only table or database owner can vacuum it
WARNING:  skipping "pg_shdepend" --- only table or database owner can vacuum it
WARNING:  skipping "pg_shdescription" --- only table or database owner can vacuum it
WARNING:  skipping "pg_auth_members" --- only table or database owner can vacuum it
WARNING:  skipping "pg_tablespace" --- only table or database owner can vacuum it
WARNING:  skipping "pg_pltemplate" --- only table or database owner can vacuum it
VACUUM

This is on x86 Linux.  8.2.6 does not exhibit the problem, or at least I haven't
run into it.  What info do I need to submit so that this can be tracked down?

Best regards,
