I've started tinkering with the FTS functionality in 8.3 and was
wondering if there was a good way to convert from a language code (like
en-us) to a language name as used in pg_ts_config.cfgname (like
'english'), As far as I know ISO639 language codes are used pretty much
everywhere else in postgres but there for some reason? I can build a
table to do the mapping if I have to, but wasn't sure if there was a
better way planned or one that was missing? (I want to build indexes
based on languages passed in from the application as language codes)
