function length(numeric) does not exist - Mailing list pgsql-bugs

Version: PostgreSQL 9.2.6, compiled by Visual C++ build 1600, 32-bit

=20

When I try to use the function length occurs the error:

=20

"ERRO: 42883: fun=E7=E3o length(numeric) n=E3o existe" (function =
length(numeric)
does not exist).

=20

Then I try to create length function:

=20

CREATE OR REPLACE FUNCTION length(tsvector)

  RETURNS int4 AS

'$libdir/tsearch2', 'tsvector_length'

  LANGUAGE 'c' IMMUTABLE STRICT;

ALTER FUNCTION length(tsvector) OWNER TO postgres;

=20

But the return is:

=20
