During some recent testing I was getting:
'WARNING: nonstandard use of \\ in a string literal'
'HINT: Use the escape string syntax for backslashes, e.g., E'\\'.'
I believe the query in question was not updated since PgSQL 7 times.
Patch attached, not heavily tested as I do not use PgSQL in production.
Maybe a dspam & PgQSL expert can check this. If PgSQL is constantly
issuing warnings, I can imagine that it slows it down a fraction.
