Re: how to escape _ in select

Hey James,

Because in future releases the default value of the
"standard_conforming_strings"
parameter will change to "on" for improved standards compliance.
You should use string constants with C-Style escapes.
Please, see
http://www.postgresql.org/docs/8.4/static/sql-syntax-lexical.html#SQL-SYNTAX-CONSTANTS
for details.

Regards,
Dmitriy
