• Backend counts: Support retrieving stats for Postgres 9.5 and older
• Log Insights: Add support for detecting aggressive vacuums (Postgres 11+)
• Parse serialization failure log events (U138 and U139)
• Have systemd restart the collector after crashes Dom Hutton #23

v0.10.0

  • Track VACUUM progress in activity snapshots
  • Activity data: Ignore backends that are not visible to the user
  • Allow additional digits for PID in pg_stat_activity Joseph Bylund
• Don't collect backend data for full snapshot anymore, this is all delegated
  to activity snapshots now

v0.9.17

• Logs: Fix regexp for 9.5 vacuum output (skip pins, but not skip frozen)
• Update to Go 1.9.1 release

v0.9.16

Release 0.9.16

v0.9.15

• Update pg_query_go / libpg_query to 9.5-1.6.2
  • Updates the query fingerprinting logic to avoid seeing different
    FETCH/DECLARE/CLOSE cursor names as unique queries - statistics on this
    are not going to be useful in most cases, and will clog the processing
    pipeline
  • Updates the query fingerprinting logic to ignore the table name for
    CREATE TEMPORARY TABLE
  • Updates the query fingerprinting logic to better handle the values list
    for INSERT statements to group complex, but similar statements together
• Support specifying db_sslmode=verify-full and passing certificate information
  using db_sslrootcert / db_sslrootcert_contents
  • The collector packages now also ship a set of known DB-as-a-Service CA
    certificates, starting with the often needed rds-ca-2015-root certificate
    (just pass that term instead of a path to db_sslrootcert)
• Support for Postgres 10
• Heroku: Support specifying configuration name in log drain endpoints
• RDS: Ensure to delete temporary log files quickly after they are submitted

v0.9.14

• Add support for Heroku logdrains
