PATH no longer a part of 7.4?

From
"Dan Langille"
Date:
The Geometric data types listed at
http://www.postgresql.org/docs/current/static/datatype-geometric.html
include a data type known as "path".  I do not see this data type in
my 7.4 installation.

Which is wrong?  The documentation or the code?

Cheers

You don't?

regression=# select * from pg_type where typname = 'path';

It is in CVS:

    test=> \dT path
                    List of data types
       Schema   |  Name  |        Description
    ------------+--------+----------------------------
     pg_catalog | "path" | geometric path '(pt1,...)'
    (1 row)

Ahhh yes, sorry, I was looking further down in the output of \dt
instead of at the top where they appear in "quotes".  Thank you.

Here is how this issue arose.  A user of:

Suse SLES 8 (aka UnitedLinux 1.0), Postgres 7.2.4 according to the
docs, however:

                                version
----------------------------------------------------------------------
--
 PostgreSQL 7.2.2 on i686-pc-linux-gnu, compiled by GCC gcc (GCC)
3.2.2

Is getting this error when creating a table named path.  I'm waiting
for details on the exact create statement, but given the application
<http://www.bacula.org/>, I suspect it is this:

create table path
(
    pathid            serial                not null,
    path              text                  not null,
    primary key (pathid)
);

The error he is getting is:

psql:<stdin>:34: NOTICE:  CREATE TABLE will create implicit sequence
'path_pathid_seq' for SERIAL column 'path.pathid'
psql:<stdin>:34: NOTICE:  CREATE TABLE / PRIMARY KEY will create
implicit
index 'path_pkey' for table 'path'
psql:<stdin>:34: ERROR:  type named path already exists

We're confused.

I've been able to create this table under 7.4.1, 7.4, and 7.3.4 (but
have no other versions under which I can test).

Thanks

Right, in 7.2 the rowtype for such a table would conflict with the
predefined type.

In 7.3 and later there is no conflict, because the predefined type name
lives in the pg_catalog schema, which is not where user tables are
customarily created.

Upgrade, or rename the path type to something else.  (Not sure if there
are any bad consequences of renaming the path type.  It'd probably be a
bad idea to do so if the database is making any actual use of the path
type, just because of potential confusion.)

Hmmm, for a 7.2 user, is there any solution?  Apart from "drop type
path"?  We'd rather not rename the table.
