I have a table with aproximately 30 columns and 45000 tuples .
When I execute (from psql) "select * from mytable" it shows me one of
the following messages:
1)Can't allocate memory
or
2) pqReadData() - backend closed the channel unexpectedly.
This probably means the backend terminated abnormally before or while
processing the request.
We have lost the connection to the backend, so further processing is
impossible. Terminating.
I also receive the message 2) when querying :
"select oid from mytable where oid >= all(select oid from mytable)"
Please, I aprecciate your help. Ana Roizen.
