PG 7.4 beta 2: COPY IN, arrays, and double quotes bug.

I spoted a trouble with the HEAD taged PG version CVS updated
on the 4th of september.

During a COPY FROM stdin query involving a VARCHAR[] column I
experienced troubles with values containing an escaped double quote.
The query was expressed like this on the application side:

"COPY my_table "
"(..., attribs) "
"FROM stdin WITH DELIMITER '\\t'"

One of the attribs value is piped to the backend as {"3/4\""}, this is
how the array appears on the wire, and PG rejected it with the
following message, as submited to syslog:

postgres[90257]: [51-1] ERROR: malformed array literal: "{"3/4""}"

Regards,
Bertrand.

P.S.: despites that this PG vresion was CVS updated after the release
of beta 2, it still identifies itself as beta1:

=> select version();
version
------------------------------------------------------------------------
PostgreSQL 7.4beta1 on i386-unknown-freebsd4.5, compiled by GCC 2.95.3
(1 row)

When PG is compiled from a CVS working directory tree, it would be
nice if the output of the version() function could include a latest
update timestamp and maybe a list of the sticky tags.
