With the introduction of PgStat_Kind PgStat_Single_Reset_Type, PgStat_Shared_Reset_Target don't make sense anymore. Replace them with PgStat_Kind. Instead of having dedicated reset functions for different kinds of stats, use two generic helper routines (one to reset all stats of a kind, one to reset one stats entry). A number of reset functions were named pgstat_reset_*_counter(), despite affecting multiple counters. The generic helper routines get rid of pgstat_reset_single_counter(), pgstat_reset_subscription_counter(). Rename pgstat_reset_slru_counter(), pgstat_reset_replslot_counter() to pgstat_reset_slru(), pgstat_reset_replslot() respectively, and have them only deal with a single SLRU/slot. Resetting all SLRUs/slots goes through the generic pgstat_reset_of_kind(). Previously pg_stat_reset_replication_slot() used SearchNamedReplicationSlot() to check if a slot exists. API wise it seems better to move that to pgstat_replslot.c. This is done separately from the - quite large - shared memory statistics patch to make review easier.

PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: https://www.postgresql.org/download/ See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions.
