Add parenthesis:
update tablea set a=10-($inputstring) where key=1;
Thus you get :
update tablea set a=10-(-1) where key=1;
instead of :
update tablea set a=10--1 where key=1;

Hi,
EXPLAIN on delete stamements works, but doesn't show me all the subsequent

You can do it by hand without dropping the column:

create sequence sales_salesid_seq;
alter table sales alter column salesid set default
nextval('sales_salesid_seq');

Yeah, that would be my interpretation: the after trigger runs just

makes it sound like the trigger invokes the PHP code synchronously,
