Hi all I just noticed a Stack Overflow question (http://stackoverflow.com/q/20124393/398670) where someone's asking how to decode '\u0000` style escapes *stored in database text fields* into properly encoded text strings. The parser supports this for escape-strings, and you can write E'\u011B' to get 'ě' because of http://postgresql.1045698.n5.nabble.com/Unicode-escapes-in-literals-td1992313.html. I don't see this exposed in a way that users can call directly, though. 'decode(bytea, text)' has the 'escape' input, but it expects octal. It's possible to use PL/PgSQL's 'EXECUTE' to use the parser to do the work, but that's downright awful. Am I missing something obvious, or is this something that'd be a good new-developer TODO?
Not sure if this is what you want?: test=> SELECT quote_literal(E'test \u011B'); quote_literal --------------- 'test ě' -- Adrian Klaver adrian.klaver@xxxxxxxxxxx
