There are no masters here. Except in replication.
I think that we should have a formatting function, but it should be developer
defined rather than pre-set, like to_char is. For example, instead of:
> select format_uuid(mypk,'format3') from tbluuid;
> and then get: {6b13c5a1-afb4-dcf5-ce8f-8b4656b6c93c}
Have:
select format_uuid(mypk,'HHHHHH-HHHH-HHHH-HHHH-HHHHHHHHHHH')
... to get the same result. Or you could even support regexes:
select format_uuid(mypk,'[0-9a-f]{6}-[0-9a-f]{6}-[0-9a-f]{6}-[0-9a-f]{6}')
... but something which allows the definition of "ad-hoc" formating masks so
that we can cover compatibility with products of which we're not yet aware.
