I need to find equivalent of Informix GLOBAL modifier in Postgresql. From Informix guide: The GLOBAL keyword indicates that the variables that follow have a scope of reference that includes all SPL routines that run in a given DB-Access or SQL administration API session.
Postgres set session "configuration parameters" have session scope:
SET only affects the value used by the current session.
Example usage:
set session "myvars.var1" = '3.1415';
...
select current_setting('myvars.var1');
