13-2.2.0

• Update to Postgres 13.8 patch release #156
• Backport Xcode 14.1 build fix from upcoming 13.9 release #156
• Fingerprinting version 3.1 #155
  • Fixes issue with "SELECT DISTINCT" having the same fingerprint as "SELECT"
    (fingerprints for "SELECT DISTINCT" will change with this revision)
  • Group additional DDL statements together that otherwise generate a lot of
    unique fingerprints (ListenStmt, UnlistenStmt, NotifyStmt, CreateFunctionStmt,
    FunctionParameter and DoStmt)
• Normalize additional DDL statements #155
  • Normalizes arguments to CreateFunctionStmt, DoStmt,
    CreateSubscriptionStmt, AlterSubscriptionStmt, CreateUserMapping and
    AlterUserMapping.
  • Note that this is different from pg_stat_statements itself, which does
    not normalize utility statements at all today.

  • Prefix errors with "deparse", and remove some asserts #131
  • Fix potential segfault when passing invalid protobuf (RawStmt without Stmt) #128

13-2.1.0

• Normalize: add funcname error object #121
• Normalize: Match GROUP BY against target list and re-use param refs #124
• PL/pgSQL: Setup namespace items for parameters, support RECORD types #123
  • This significantly improves parsing for PL/pgSQL functions, to the extent
    that most functions should now parse successfully

13-2.0.7

• Normalize: Don't modify constants in TypeName typmods/arrayBounds fields (#118)
  • This matches how pg_stat_statement behaves, and avoids causing parsing
    errors on the normalized statement
• Don't fail builds on systems that have strchrnul support (FreeBSD)

13-2.0.6

• Normalize: Don't touch "ORDER BY 1" expressions, keep original text #115
  • This avoids obscuring the semantic meaning of integers in the ORDER BY
    clause, which is to reference a particular column in the target list.

13-2.0.5

• Update to Postgres 13.3 patch release #114
• Add optional Makefile target to build as shared library #100
• Normalize: Don't touch "GROUP BY 1" type statements, keep original text #113
  • This avoids obscuring the semantic meaning of integers in the GROUP BY
    clause, which is to reference a particular column in the target list.
• Fingerprint: Cache list item hashes to fingerprint complex queries faster #112
  • This was exhibiting quite bad runtime behaviour before, causing both an
    explosion in memory, as well as very high CPU runtime for complex queries.
  • The new approach ensures we don't calculate the hashes for a particular
    list more than once, which ensures that we roughly have quadratic runtime
    instead of exponential runtime.
• Deparser: Emit the RangeVar catalogname if present #105
• Fix crash in pg_scan function when encountering backslash escapes #109
• Integrate oss-fuzz fuzzer #106

13-2.0.4

• Deparser: Fix crash in CopyStmt with HEADER or FREEZE inside WITH parens
  • The parse tree does not contain an explicit argument in those cases,
    but does when specified in the legacy mode without the wrapping WITH.
  • With this change we only output the "1" argument when the original tree
    also had this, to ensure parse tree comparisons match. Note the intent
    here is technically the same, which is to enable these options.

13-2.0.3

• Normalize: Fix handling of two subsequent DefElem elements #96
  • We were incorrectly adding too many DefElem locations to the recorded
    constant values, causing a crash when more than a single DefElem
    is present in a utility statement.
