Re: Trouble Escaping Quotes

Below is logging information from a client-side SQL monitor, as well as what
I found in <posgresqlhome>/data/serverlog:

I this particular instance the offending quote is in the problem_desc field.
The value of problem_desc being "Bob's Problem" (double quotes excluded).

*** Client-Side SQL monitor data ***
SET TRANSACTION ISOLATION LEVEL READ COMMITTED;SET DATESTYLE TO ISO;BEGIN;
insert into "rmas"
  ("id", "company_id", "repair_types_id", "printer_models_id",
"serial_number", "problem_desc")
values
  (1240916, 126, 3, 595, '45845384568', 'Bob''s Problem')
Command executed sucessfully
1 row(s) affected
Commiting transaction
END;
SELECT send_rma(rma_info) FROM rma_info WHERE rma = 1240916
server closed the connection unexpectedly
    This probably means the server terminated abnormally
    before or while processing the request.

         This probably means the server terminated abnormally

The connection to the server was lost. Attempting reset: WARNING:
