Andrew Dunstan	b3b4d8e68a	Move Perl test modules to a better namespace ... The five modules in our TAP test framework all had names in the top level namespace. This is unwise because, even though we're not exporting them to CPAN, the names can leak, for example if they are exported by the RPM build process. We therefore move the modules to the PostgreSQL::Test namespace. In the process PostgresNode is renamed to Cluster, and TestLib is renamed to Utils. PostgresVersion becomes simply PostgreSQL::Version, to avoid possible confusion about what it's the version of.

Michael Paquier	f9c4cb6868	Add more $Test::Builder::Level in the TAP tests ... Incrementing the level of the call stack reported is useful for debugging purposes as it allows to control which part of the test is exactly failing, especially if a test is structured with subroutines that call routines from Test::More. This adds more incrementations of $Test::Builder::Level where debugging gets improved (for example it does not make sense for some paths like pg_rewind where long subroutines are used). A note is added to src/test/perl/README about that, based on a suggestion from Andrew Dunstan and a wording coming from both of us. Usage of Test::Builder::Level has spread in 12, so a backpatch down to this version is done.

Andrew Dunstan	201a76183e	Unify PostgresNode's new() and get_new_node() methods ... There is only one constructor now for PostgresNode, with the idiomatic name 'new'. The method is not exported by the class, and must be called as "PostgresNode->new('name',[args])". All the TAP tests that use PostgresNode are modified accordingly. Third party scripts will need adjusting, which is a fairly mechanical process (I just used a sed script).	5 years ago

Amit Kapila	3fa17d3771	Use HTAB for replication slot statistics. ... Previously, we used to use the array of size max_replication_slots to store stats for replication slots. But that had two problems in the cases where a message for dropping a slot gets lost: 1) the stats for the new slot are not recorded if the array is full and 2) writing beyond the end of the array if the user reduces the max_replication_slots. This commit uses HTAB for replication slot statistics, resolving both problems. Now, pgstat_vacuum_stat() search for all the dead replication slots in stats hashtable and tell the collector to remove them. To avoid showing the stats for the already-dropped slots, pg_stat_replication_slots view searches slot stats by the slot name taken from pg_replication_slots. Also, we send a message for creating a slot at slot creation, initializing the stats. This reduces the possibility that the stats are accumulated into the old slot stats when a message for dropping a slot gets lost.

Amit Kapila	f5fc2f5b23	Add information of total data processed to replication slot stats. ... This adds the statistics about total transactions count and total transaction data logically sent to the decoding output plugin from ReorderBuffer. Users can query the pg_stat_replication_slots view to check these stats.
