v0.14.2

• Log parser: Add support for offset-based timezone identifier
  • Previously we assumed that Postgres always outputs the timezone name,
    that is not correct for some timezones, where instead an offset like
    "+0100" would be printed.

v0.14.1

• Fixes to experimental sequences report
• Document monitoring helper functions for sequences report

v0.14.0

• Introduce once-per-minute query statistics collection
  • Enabled for PostgreSQL 9.4+
  • This replaces the old logic for query stats without text (statement_text_frequency),
    and is always active
  • Statistics data gets sent with every full snapshot
• 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

v0.13.1

• Don't error out on pg_stat_replication.replay_lsn being NULL #21

v0.13.0

• Support basic vacuum information for Postgres 9.5 and older
• Track connection counts per database and per role
• Add ignore_table_pattern / IGNORE_TABLE_PATTERN option
• Avoid errors when collecting from AWS Aurora for Postgres instances
• Log Insights improvements
  • Better setup help
  • Increase read rate for RDS log downloader from 100 to 1000 lines
  • Add support for extracting EXPLAIN plans from auto_explain output
  • Fix autovacuum, autoanalyze and checkpoint completed parsing for PG 10
  • Avoid sending unparsed explain text for truncated log lines
  • Detect vacuum/analyze skipped log lines

v0.12.0

• Associate truncated queries to the correct error fingerprint
• Update to Go 1.9.3

v0.10.0

• Update pg_query_go to Postgres 10 and fingerprint version 2
  • This is a breaking change in collector output, as queries will now
    be fingerprinted differently
• Activity snapshots
  • Use pg_stat_activity helper when it exists
  • 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
• Update to Go 1.9.2
• RDS pgss check: Add additional safety against nil pointer dereferences

v0.9.17

• Logs: Fix regexp for 9.5 vacuum output (skip pins, but not skip frozen)
• Update to Go 1.9.1 release
• Allow disabling collection of relation/schema information
