I believe so some features - like advanced formatting will be accepted
sometime. Macros are little bit different story - it is relative
difficult implement them in current psql, because code is complex -
there are unclean and unreadable support of readline and interactive
mode. I had a idea of noninteractive console, that can support macros
- but there are lot of issues still. I would to work on some better
integration between client and server inlined procedures, and on
simpler using psql from bash. Implementing own full macro language is
not necessary. Probably better way is enable extending console
statements with possibility to call external scripts.
