Hi Michael,
Thank you for your reply.
We had read the LIKE doc but obviously missing the fact that
"the backslash already has a special meaning in string
literals, so to write a pattern constant that contains a backslash you
must write two backslashes in an SQL statement. Thus, writing a
pattern that actually matches a literal backslash means writing four
backslashes in the statement. "
Mickael.

See the "Pattern Matching" section in the "Functions and Operators"
chapter of the documentation:
http://www.postgresql.org/docs/8.0/static/functions-matching.html
The documentation under "LIKE" discusses issues regarding the escape
character (the backslash by default).
