[SQL] Setting session global variables

[Kyle]

Is there a way to set a session global variable in PostgreSQL?  The only thing I see are examples of setting config variables. Not sure if session variables are your best solution, but here's how you implement them: -- Warning: this defines a global variable in the tcl interpretor.  This could -- crash with other TCL procedures if the same name were used during the same connection. -- Store a value in a variable.  This is helpful for caching values in a transaction -- Calling sequence: store(variable,value) create function store(text,text) returns int4 as '     global store_vars     return [set store_vars($1) $2]     ' LANGUAGE 'pltcl'; -- Fetch a value from a variable. -- Calling sequence: recall(variable) create function recall(text) returns int4 as '     global store_vars     return [subst $store_vars($1)]     ' LANGUAGE 'pltcl';
