Hi. I propose to add "accumulative" flag to a function definition. This flag would be set for function f(x) which is accumulative and immutable.
This flag allows to use an index on x for clauses containing f(x): where f(x) = const where f(x) > const and so on. -- ------------ pasman -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
