Use 'revision_id' as a tiebreaker in case creation_date is the same, which can happen if different revisions were created inside a single transaction.

Reduced generation of dead tuples in postgres.

Background: In the old version, the fields latest and live

revisions were updated always via two separate dmlDML statements.

Every update causes in PostgreSQL (tested to pg 9.6) one more dead

tuple, such that on busy systems, we see 30k + dead tuples per

hour. These dead tuples in turn cause more auto vacuum operations

and can lead to abandoned query plans.

This change can reduce the number of dead tuples on cr_items into

half, by allowing both fields to be set in one operation (namely

content_item__set_live_revision). This function has an optional 4th

argument that can cause this optimization. For legacy applications,

nothing changes.

Btw: since all commonly used applications use the live revision, the

fallback of the latest_revision is unused. One can consider to

remove the cr_revision_latest_tr, at least on on certain

installations.

bump revision to 5.1.9d23

Content-Repository Reform : Reduction of number of functions in

the content repository for PostgreSQL by using using argument defaults

(while providing compatibility for clients using old versions):

- reduced number of versions of content_item__new from 12 (!) to 6 by using defaults

- commented differences

- commented arguments of plpgsql functions with long argument lists

- reduced code duplication by basing one version of content_item__new/17 directly on /20

- marking on version of content_item__new/17 and content_item__new/6 as deprecated

- reduced number of versions of content_revision__new from 7 to 4 by using defaults

- commented differences

- marking on version of content_revision__new/7 as deprecated

- let automatically generated functions call directly content_revision__new/13

- remove space from automatically generated functions

- updated automatically generated functions for all types of the content repository

- reduced number of versions of image__new from 4 to 2by using defaults

- reduced number of versions of image__new_revision from 2 to 1 by using defaults

Scalability reform part 3 (content-repository):

- content_revision__del:

* Removed manual nulling of live_revision and latest_revision

by using appropriate ond delete actions on foreign keys

* Removed manual deletion of old_revision and new_revision in

cr_item_publish_audit by using "on delete cascade"

- content_item__del:

* Removed manual deletion of item_id in cr_item_publish_audit

by using "on delete cascade"

* Removed manual deletion of item_id in cr_release_periods

by using "on delete cascade"

* Removed manual deletion of item_id in cr_item_template_map

by using "on delete cascade"

* Removed manual deletion of item_id in cr_item_keyword_map

by using "on delete cascade"

* Removed manual deletion of direct permissions (was already

cascading)

- Added missing index for child_id to cr_child_rels.

This index was in the create scripts (with a non-conformant name),

but not in the upgrade scripts

- bump version number of acs-content-repository to 5.9.0d3

Bring PostgreSQL functions closer to the current level of PL/pgSQL:

- upgrade PL/pgSQL functions to the $$ notation (recommended since pg8.0, jan 2005).

- get rid of backslash usages in function definitions

- drop aliases in favor of named function arguments (recommended since pg8.0)

- fix wrong function_args, add missing function_args, align default semantics

with the defaults in pg (providing "null" as default means the argument is

optional).

- change return types of triggers from "opaque" to "trigger" (recommended since pg8.0)

- unify names of triggers *_tr

- removed some version dependencies of pg 7.2 and 7.3

fix laundry list of bugs in content repository copy code.

duplicate version of the 11arg content_folder__new

copy_creation_ip rather than copy__creation_ip in content_revision__copy

content_folder__copy did not preserve context_id properly

content_item__copy2 had a bunch of unused varaibles -- removed them.

content_item__copy now preserves live_revision so things which copy an

item with a live revision to not have to explicitly publish the new copy

(which eg file storage did not do).

content_revision__copy did an insert into acs_objects without specifying

column names which breaks on a new install since the order is not as expected.

Added define_function_arg calls to non-content-revision objects and to

create_type and create_attributes, so we can do these operations via

Tcl. Content revisions, due to LOB/non-LOB issues and the incompatibility

of LOB operations between DBs need their own "smart" Tcl API.

content_item__is_subclass: did not short curcuit loop when subclass found
