What do you guys do to namespace your functions so that they are not
jumbled in with the system functions and also somewhat hierarchically
organized.
Obviously it's possible to create schemas for different namespaces but that
can lead to a lot of schemas which hold no data. The other way is to
simply name your functions like _lib_etl_csv_import_weird_data_format but
that's not too much fun either.
Just curious how other people deal with the issue.
