Some people use temporary tables for storing such values. Another
way would be to write set/get functions in a language that supports
global storage (PL/Perl, PL/Tcl, PL/Python, etc.). See for example
the set_var() and get_var() functions in the PL/Perl documentation:
http://www.postgresql.org/docs/8.0/static/plperl-global.html
