Обсуждение: text(bool) not defined

I've noticed that text(bool) isnt a defined function (nor does
'true'::bool::text work). 

It would be great to have this defined.

Since "select 'false'::bool" gives 'f' and "select 'true'::bool" gives
't', perhaps text(bool) should return 't' or 'f'.

A case can, also, be given for returning 'true' or 'false'.

ps. 7.1.2 on solaris
pps. "select boolin(true)" causes the backend to core.

case when value then 'answer if true' else 'answer if false' end
