Hello All,
Apologies if this is a bit off-topic. Any hints as to what character
sequences need escaping in Postgres's regular expressions?
Let me show you the problem.
If I want to find all strings that start with 'postgres' I use the regex
select str ~ '^postgres'.
However if str contains reserved meta characters, e.g. +(-)[.]{} etc
then I need to escape that sequence somehow? e.g. to find a string
starting 'fish + chips' I need to escape for regex and then postgres.
select str ~ '^fish\\s\\+\\schips''
Has anyone got a definitive list of replacements that are required for
Postgres's version of Regular Expressions?
Howard.
