Hi!

Why when I prepare statement by parsing such query: 'SELECT * FROM
"test" WHERE "ind" < $1 + 1' ("ind" is of type REAL) $1 is interpreted
by backend as INTEGER? Parse completed successfully, but trying to bind
parameter as '20.20' resulted in "ERROR C22P02 Minvalid input syntax for
integer: "20.20" Fnumutils.c L98 Rpg_atoi"? I understand that it's
possible to make query like 'SELECT * FROM "test" WHERE "ind" < $1::real
+ 1', but at the query building time I can't know what type this column is!
