Обсуждение: remove TCL_ARRAYS

This patch removes the TCL_ARRAY symbol.  This seems to be a leftover
from when pgtcl was around in the backend; if enabled, it causes
array_out to emit bogus array values:

alvherre=# create table bar ( a text);
CREATE TABLE
alvherre=# insert into bar values ('foo"');
INSERT 0 1
alvherre=# select array_append('{}', a) from bar;
 array_append
--------------
 {"foo""}
(1 ligne)

The correct value is

alvherre=# select array_append('{}', a) from bar;
 array_append
--------------
 {"foo\""}
(1 ligne)


Of course, the system does not accept the TCL_ARRAY value back.

If you're going to remove it you should actually remove it
(eg from pg_config_manual.h).

Yeah, it was supporting some kluge or other in the libpgtcl client.
AFAICT from the 7.x code, the client-side kluge was never enabled by
default anyway, so it seems unlikely anyone will miss it.

Oops.  Thanks, removed from there too.
