Undocumented FLOAT data type

I just noticed the SQL-92 FLOAT datatype is implemented in the grammar but is
not documented in the manual.

By the way, what was the ANSI/ISO SQL committee thinking when they made up
perverse names like "CHARACTER VARYING"? (Not to mention all the functions
that require special grammar rules just to parse...)

It's in the 7.1 manual.

There is strong evidence that they were only thinking a small fraction of
the total time.

I can't seem to find it on the web page:

http://postgresql.readysetnet.com/devel-corner/docs/postgres/datatype.html

or in the head branch datatype.sgml file.

There is "real", "double precision", "float4", and "float8", but no "float".

Ooops.
