Hey, a client of ours has been having some data corruption in their database. We got the data corruption fixed and we believe we've discovered the cause (they had a script killing any waiting queries if the locks on their database hit 1000), but they're still getting errors from one table:
pg_dump: SQL command failed
pg_dump: Error message from server: ERROR: invalid memory alloc request size 18446744073709551613
pg_dump: The command was: COPY public.foo (<columns>) TO stdout;
That seems like an incredibly large memory allocation request - it shouldn't be possible for the table to really be that large, should it? Any idea what may be wrong if it's actually trying to allocate that much memory for a copy command?
