Re: Incomplete pg_dump operation

xyz is the largest table in the database, and the one identified in prior error messages.

After su'ing to pgsql, I executed a:

    pg_dump -t xyz database_name > /usr/local/pgsql/db_backups/database_name-Manual-Xyz-Table-Dump

command, and this message was returned:

    pg_dump: ERROR:  could not open relation with OID 2196359751
    pg_dump: SQL command to dump the contents of table "xyz" failed: PQendcopy() failed.
    pg_dump: Error message from server: ERROR:  could not open relation with OID 2196359751
    pg_dump: The command was: COPY public.xyz ({various field names}) TO stdout;

That's the same OID other error messages have complained about.

About 1/3 of the database was dumped to the destination file before this error message was displayed.
