pgrecon 0.2.0

pgrecon converts now.

• pgrecon convert emits PostgreSQL DDL from the inventory, offline:
  tables under a documented type mapping, primary and unique keys,
  checks, foreign keys, and secondary indexes; everything the
  converter cannot port faithfully lands in a residue report naming
  the object and the reason instead of becoming wrong DDL.
• Partition bounds are extracted (HIGH_VALUE through the same chunked
  path as check conditions, subpartitions included) and converted to
  native partition children: RANGE with MAXVALUE, LIST with DEFAULT,
  HASH with MODULUS/REMAINDER, and composite shapes. Interval-driven
  creation carries a note pointing at scheduled creation such as
  pg_partman.
• The rest of schema structure converts: sequences restarted at their
  extracted position with bigint-safe bounds, schema-local synonyms
  as updatable views, database links scaffolded as oracle_fdw
  servers, column defaults, and virtual columns as generated columns.
• The converter grows a code lane: standalone functions and
  procedures whose every construct is provably equivalent convert
  mechanically to PL/pgSQL, comments and formatting carried through.
  SELECT INTO becomes INTO STRICT so NO_DATA_FOUND still raises;
  cursor%ROWTYPE becomes a record variable; NVL, SYSDATE, sequence
  NEXTVAL, DBMS_OUTPUT.PUT_LINE, EXECUTE IMMEDIATE, q-quoted
  literals, and FROM DUAL all translate. Everything semantic refuses
  by name and line into the residue report, and a routine that calls
  a refused routine is refused with it. Function bodies are validated
  by PostgreSQL itself: the emitted DDL applies with
  check_function_bodies on, never disabled.
• Views transpile with (+) outer joins folded to ANSI; CONNECT BY,
  database-link reads, and object-relational methods refuse with
  named reasons.

The full output of the test estates applies to a live PostgreSQL 16
at zero errors, and the converted routines were executed there to
confirm behavior. See CHANGELOG.md for details.
