Waiting for PostgreSQL 15 – Add assorted new regexp_xxx SQL functions.

On 3rd of August 2021, Tom Lane committed patch:

Add assorted new regexp_xxx SQL functions.
 
This patch adds new functions regexp_count(), regexp_instr(),
regexp_like(), and regexp_substr(), and extends regexp_replace()
with some new optional arguments.  All these functions follow
the definitions used in Oracle, although there are small differences
in the regexp language due to using our own regexp engine -- most
notably, that the default newline-matching behavior is different.
Similar functions appear in DB2 and elsewhere, too.  Aside from
easing portability, these functions are easier to use for certain
tasks than our existing regexp_match[es] functions.

Waiting for PostgreSQL 15 – Allow publishing the tables of schema.

On 27th of October 2021, Amit Kapila committed patch:

Allow publishing the tables of schema.
 
A new option "FOR ALL TABLES IN SCHEMA" in Create/Alter Publication allows
one or more schemas to be specified, whose tables are selected by the
publisher for sending the data to the subscriber.
 
The new syntax allows specifying both the tables and schemas. For example:
CREATE PUBLICATION pub1 FOR TABLE t1,t2,t3, ALL TABLES IN SCHEMA s1,s2;
OR
ALTER PUBLICATION pub1 ADD TABLE t1,t2,t3, ALL TABLES IN SCHEMA s1,s2;
 
A new system table "pg_publication_namespace" has been added, to maintain
the schemas that the user wants to publish through the publication.
Modified the output plugin (pgoutput) to publish the changes if the
relation is part of schema publication.
 
Updates pg_dump to identify and dump schema publications. Updates the \d
family of commands to display schema publications and \dRp+ variant will
now display associated schemas if any.

Waiting for PostgreSQL 15 – Revoke PUBLIC CREATE from public schema, now owned by pg_database_owner.

On 10th of September 2021, Noah Misch committed patch:

Revoke PUBLIC CREATE from public schema, now owned by pg_database_owner.
 
This switches the default ACL to what the documentation has recommended
since CVE-2018-1058.  Upgrades will carry forward any old ownership and
ACL.  Sites that declined the 2018 recommendation should take a fresh
look.  Recipes for commissioning a new database cluster from scratch may
need to create a schema, grant more privileges, etc.  Out-of-tree test
suites may require such updates.
