Changelog

All versions are tagged by the major Postgres version, plus an individual semver for this library itself.

10-1.0.2

  • Avoid compiler warning due to unused result in pg_query_parse_plpgsql

10-1.0.1 2017-10-31

  • Fix fingerprint tests

10-1.0.0 2017-10-30

  • First release based on PostgreSQL 10.0
    • Parse tree output may have changed in backwards-incompatible ways!
    • Fingerprint base version bumped to "02" to reflect the change in parse trees

9.5-1.7.1 2017-10-26

  • Allow "$1 FROM $2" to be parsed
    • This is new with Postgres 10 output of pg_stat_statements, so we should treat this the same as "? FROM ?" in earlier versions.

9.5-1.7.0 2017-10-20

  • Update to Postgres 9.5.9
  • Support gcc versions earlier than 4.6.0
  • Export version information in pg_query.h directly

9.5-1.6.2 2017-07-30

  • Fingerprinting Version 1.3
    • Attributes to be ignored:
      • RangeVar.relname (if node also has RangeVar.relpersistence = "t")
    • Special cases: List nodes where parent field name is valuesLists
      • Follow same logic described for fromClause/targetList/cols/rexpr

9.5-1.6.1 2017-07-29

  • Fingerprinting Version 1.2
    • Ignore portal_name in DeclareCursorStmt, FetchStmt and ClosePortalStmt

9.5-1.6.0 2017-07-29

  • Change normalization methods to output $1/$2 .. $N instead of ? characters
    • BREAKING CHANGE in pg_query_normalize(..) output
    • This matches the change in the upcoming Postgres 10, and makes it easier to migrate applications to the new normalization format

9.5-1.5.0 2017-05-26

  • Update to Postgres 9.5.7
  • Disable 128-bit integer support (they are not used), to support 32-bit archs @herwinw
  • Cleanup efforts @herwinw
    • Improve concurrency tests
    • Make sure we have a valid proc_source
    • Normalized whitespace in pg_query_parse_plpgsql
    • Move inclusion of stdio.h in plpgsql parser

9.5-1.4.2 2016-12-06

  • Cut off fingerprints at 100 nodes deep to avoid excessive runtimes/memory
  • Fix warning on Linux due to missing asprintf include

9.5-1.4.1 2016-06-26

  • Automatically call pg_query_init as needed to ease threaded usage

9.5-1.4.0 2016-06-26

  • Clean up includes to avoid dependency on stdbool.h and xlocale.h
  • Change PL/pgSQL input to be the full CREATE FUNCTION statement
    • This is necessary for parsing, since we need the argument and return types
  • Fingerprinting Version 1.1
    • Only ignore ResTarget.name when parent field name is targetList and we have a SelectStmt as a parent node (fixes UpdateStmt fingerprinting)
  • Normalize the password in ALTER ROLE ... PASSWORD '123' statements
  • Make library thread-safe through thread-local storage #13

9.5-1.3.0 2016-05-31

  • Extract source code using LLVM instead of manually compiling the right objects
    • This speeds up build times considerably since we don't download the Postgres source anymore, instead shipping a partial copy created as part of a release.
  • Experimental support for parsing PL/pgSQL source code (output format subject to change)

9.5-1.2.1 2016-05-17

  • Make sure we encode special characters correctly in JSON output (@zhm #11)

9.5-1.2.0 2016-05-16

  • Fix stack overflow when parsing CREATE FOREIGN TABLE (#9)
  • Update to PostgreSQL 9.5.3

9.5-1.1.0 2016-04-17

  • Add pg_query_fingerprint() method that uniquely identifies SQL queries, whilst ignoring formatting and individual constant values
  • Update to PostgreSQL 9.5.2

9.5-1.0.0 2016-03-06

  • First release based on PostgreSQL 9.5.1
  • Make JSON_OUTPUT_V2 the default and remove outfuncs patch
    • NOTE: This is a backwards incompatible change in the output parsetree format!

9.4-1.0.0 2016-03-06

  • First tagged release based on PostgreSQL 9.4.5
