Thanks Oleg!

Did as you recommended:

set_curcfg('default');

got new error running query containing:
to_tsquery('advanced|tech');rank(avectors,a2);

ERROR:  ExecMakeTableFunctionResult: expression is not a function call

Past message board suggests this is a pg error, not tsearch2 -- do you know
of any workarounds?

Thanks for all your help Oleg,

Dan
