that looks like EAV. is it?

that's not going to work.

perhaps you can rewrite the from part to only return one row for every
table1_fk,  this one row will combine several rows from table2

will only work if the optimiser picks index join on table 1

to do it with an update statement you need no more than one rows in the
from for each row in the target.

easiest non update statement approach is probably to use a plpgsql 
function with a loop.

basically you need to find another way to do it.
