PGDOCS - Replica Identity quotes

PGDOCS - Replica Identity quotes

Hi,

Here are some trivial quote changes to a paragraph describing REPLICA IDENTITY.

These changes were previously made in another ongoing R.I. patch
v28-0001 [1], but it was decided that since they are not strictly
related to that patch they should done separately.

======
logical-replication.sgml

Section 31.1 Publication

A published table must have a “replica identity” configured in order
to be able to replicate UPDATE and DELETE operations, so that
appropriate rows to update or delete can be identified on the
subscriber side. By default, this is the primary key, if there is one.
Another unique index (with certain additional requirements) can also
be set to be the replica identity. If the table does not have any
suitable key, then it can be set to replica identity “full”, which
means the entire row becomes the key. This, however, is very
inefficient and should only be used as a fallback if no other solution
is possible. If a replica identity other than “full” is set on the
publisher side, a replica identity comprising the same or fewer
columns must also be set on the subscriber side. See REPLICA IDENTITY
for details on how to set the replica identity. If a table without a
replica identity is added to a publication that replicates UPDATE or
DELETE operations then subsequent UPDATE or DELETE operations will
cause an error on the publisher. INSERT operations can proceed
regardless of any replica identity.

Suggested changes:

1.
The quoted "replica identity" should not be quoted -- This is the
first time this term is used on this page so I think it should be
using <firstterm> SGML tag, just the same as how
<firstterm>publication</firstterm> looks at the top of this section.

2.
The quoted "full" should also not be quoted. Replicate identities are
not specified using text string "full" - they are specified as FULL
(see [2]), so IMO these instances should be changed to
<literal>FULL</full> to eliminate that ambiguity.

~~~

PSA patch v1 which implements the above changes.
