Well, that might well explain the failure. pg_dump does suck a lot of
schema information into memory at startup, but 540m seems excessive.
Maybe you've found a memory leak in pg_dump (it wouldn't be the first
one). Does this database have a particularly large number of objects?
regards, tom lane
I wouldn't call it large - 27 tables, 111 functions, 21 custom types
(used for set returning function results).
The biggest row count table has about 200k records (structure is
int,int,timestamp)
The biggest physical table is the one thats failiing. The table itself
is physically 81m and its toast table is 82m.
