escape string syntax and pg_dumpall

I just ran pg_dumpall from today's CVS against a 14 April server - I got:

pg_dumpall: query failed: ERROR: type "e" does not exist
pg_dumpall: query was: SELECT spcname, pg_catalog.pg_get_userbyid(spcowner) AS spcowner, spclocation, spcacl FROM pg_catalog.pg_tablespace WHERE spcname NOT LIKE E'pg\_%'

That comes from v1.62 of pg_dumpall.c :

res = executeQuery(conn, "SELECT spcname, "
"pg_catalog.pg_get_userbyid(spcowner) AS spcowner, "
"spclocation, spcacl "
"FROM pg_catalog.pg_tablespace "
"WHERE spcname NOT LIKE E'pg\\_%'");

Add E'' syntax so eventually normal strings can treat backslashes
literally.

Add GUC variables:

"escape_string_warning" - warn about backslashes in non-E strings
"escape_string_syntax" - supports E'' syntax?
"standard_compliant_strings" - treats backslashes literally in ''

Update code to use E'' when escapes are used.
----------------------------

My version of the server predates those GUC settings - could the code
be assuming that my server can cope with something it can't?
(Normally I would just upgrade everything - and I bet it will work -
but, I think we still recommend that people use new pg_dumpall to
dump their old server when upgrading..)

Cheers,
