Hello!
I'm working with Posgresql 7.0.3 on Red Hat linux 6.2. When I make the
following query "select * from mytable" (2000000 rows), I get the message:
"Backend sent D message whitout prior T" or
"Backend sent B message whitout prior T"
What is the problem?
Plese help me
Thanks

You're running out of application memory for the query result. (libpq
doesn't recover from that too gracefully, unfortunately.) Consider
using a cursor to fetch the data in more manageable chunks.
