Appendix I. ConfiguringPostgres Pro for1C Solutions

You can install and usePostgres Pro with1C solutions in a client/server model. For optimal performance and stability, modify the following settings in thepostgresql.conf configuration file ofPostgres Pro server:

  1. Increase the maximum number of allowed concurrent connections to the database server, up to 1000 connections.1C solutions can open a large number of connections, even if not all of them are used, so it is recommended to allow not less than 500 connections.

    max_connections = 1000

  2. To ensure that temporary tables are handled correctly, modify the following parameters:

    • Increase the buffer size for temporary tables:

      temp_buffers = 32MB

    • Increase the number of allowed locks of tables or indexes per transaction to 256:

      max_locks_per_transaction = 256

      Typically,1C solutions use a lot of temporary tables. Every backend process usually contains multiple temporary tables. When closing a connection,Postgres Pro tries to drop all temporary tables in a single transaction, so this transaction may use a lot of locks. If the number of locks exceeds themax_locks_per_transaction value, the transaction will fail, leaving multiple orphaned temporary tables.

  3. Enable backslash escapes in all strings, and switch off the warning about using the backslash escape symbol:

    standard_conforming_strings = offescape_string_warning = off

  4. Set theeffective_cache_size parameter to at least half ofRAM available on the system.Postgres Pro query optimizer performance depends on the amount of allocatedRAM.

  5. Optimize query planning usingonline_analyze andplantuner extensions, as follows:

    • Addonline_analyze andplantuner to theshared_preload_libraries variable.

      shared_preload_libraries = 'online_analyze, plantuner'
    • Enable automatic analysis of temporary tables when they are modified:

      online_analyze.table_type = 'temporary'
    • TunePostgres Pro optimizer to improve planning for recently created empty tables:

      plantuner.fix_empty_table = 'on'
    • Suppress detailed messages from theonline_analyze extension:

      online_analyze.verbose = 'off'
