Current CVS has strange parser for float type

Works here:

test=> select 5.3::float;
float8
--------
5.3
(1 row)

Very strange or I missed something?
This 'feature' appears only on FreeBSD, Linux works fine.

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to majordomo@postgresql.org)

Could it be something with locales ?

Try:

select 5,3::float;

It's locale.

Oooh, bingo! On HPUX:

regression=# select 5.3::float;
float8
--------
5.3
(1 row)

regression=# set lc_numeric = 'de_DE.iso88591';
SET
regression=# select 5.3::float;
ERROR: Bad float8 input format '5.3'

I think this is a consequence of the changes made a little while back
(by Peter IIRC?) in locale handling. It used to be that we deliberately
did *not* allow any LC_ setting except LC_MESSAGES to actually take
effect globally in the backend, and this sort of problem is exactly
why. I think we need to revert some aspects of that change.

Bruce, this is a "must fix" open item ...

Does it accept '5,4'::float? Try running initdb with --locale=C.

Yup. I've applied a fix in pg_locale.c. Turns out the code was trying
to do the right thing, but failed because setlocale() returns pointers
to modifiable static variables :-(

Yes, it accepted '5,4'::float format.
