Thread: set variable for TOAST_TUPLE_THRESHOLD

Hi

I would like to test, how storing one biggish (~450 bytes bytea) column
into toast table would affect my applications performance.

is there a way to set the values used for this using some SET variable
or some column in system tables.

or is my only option to build a custom version of server with changed 
TOAST_TUPLE_THRESHOLD/TOAST_TUPLE_TARGET (in
src/include/access/tuptoaster.h) as advised by Tom Lane in
http://listcrawler.com/message2.jsp?id=53577
