Bytea(precision)

Recently, while testing the application compatibility of the ODBC driver
in , we have come across a problem. Some applications, specifically
MS Project, want to create tables using a bounded binary data type.
(i.e. SQL_BINARY) Up to now, we have mapped ODBC's SQL_BINARY to
PostgreSQL's BYTEA. The problem is that when the application tries to
create the table. Example:

CREATE TABLE foo (bar BYTEA(100));

PostgreSQL errors, complaining about the "(". I have created a
patch, which I am now testing, to allow this syntax for BYTEA. It also,
truncates to the specified precision in the same fashion as does VARCHAR
while preserving its original behavior when a precision is not
specified.

1. Are there any objections?

2. It is very light weight and I would like to get the patch into
6.4.1. Is this possible? (I do not know the plans for this 6.4.1)
