Re: [HACKERS] proposal: schema variables

[Serge Rielau]

" Although the syntax of CREATE TEMPORARY TABLE resembles that of the SQL 
standard, the effect is not the same. In the standard, temporary tables are 
defined just once and automatically exist (starting with empty contents) in 
every session that needs them. PostgreSQL instead requires each session to 
issue its own CREATE TEMPORARY TABLE command for each temporary table to be 
used. This allows different sessions to use the same temporary table name for 
different purposes, whereas the standard's approach constrains all instances of 
a given temporary table name to have the same table structure.”
Yeah, that’s a DECLAREd table in my book. No wonder we didn’t link up.
