Обсуждение: Inconsistent casts

Since almost every cast to "text" is implicit, then I believe so should

inet -> text
macaddr -> text
int4 -> varchar
int8 -> varchar

which are currently not.

Also, some casts seem to be missing; numeric -> text, for example.

I would like to see us *eliminate* implicit casts to text.  Not add more.

See my prior rants on subject... but the core of the matter is that if
every datatype can be implicitly casted to text then you have no type
safety worthy of the term.  We have open bug reports that reduce to this.
