Thread: hstore isexists
Before we spring hstore on an unsuspecting world as a contrib module, in the interests of good English, is it too late to change "isexists" to simply "exists"? cheers andrew

It's possible to create function 'exists' and mention only it in docs.

All the rest look ok to me. cheers andrew
'exists' isn't a good name for function :(. From gram.y:
col_name_keyword:...
function_name: IDENT { $$ = $1; } | unreserved_keyword
{ $$ = pstrdup($1); } | func_name_keyword { $$ = pstrdup($1); } ;
So call of function named 'exists' should be in quotas:
select "exists"('a=>1','a');

Yeah, that isn't going to work. Perhaps "ifexists"? Or just leave well
enough alone.

Seems a bit ugly, but better than isexists or ifexists ...

But it seems like bad practice and unnecessary clutter to start off by deprecating something. cheers andrew

Sorry, I don't know the history of hstore... but if it's brand new, why are we worried about backwards compatibility? -- Jim Nasby jim@nasby.net EnterpriseDB http://enterprisedb.com 512.569.9461 (cell)

Because it's been available for awhile outside of contrib (namely,
on Oleg and Teodor's own site). So there are people using it.

So there are people using it. So wouldn't it make sense to document that the old functions are depricated so those existing users will stop using them? Maybe the base documentation isn't the best place for that... perhaps an UPGRADING section. -- Jim Nasby jim@nasby.net EnterpriseDB http://enterprisedb.com 512.569.9461 (cell)
