Wraps the v1.0 PG-wire deliverable with the two pieces operators
actually look for: a runnable example PRG and an updated CI gate
list in CLAUDE.md.
* examples/pgserver_demo.prg — full bootstrap PRG demonstrating
every HB_FUNC composed in the order a production deployment
needs:
PG_TLS_SELF_SIGNED → PG_ADD_ROLE × N → PG_ALLOW_IP × N →
PG_SERVER_START( ":5432", "md5" )
Comments cover the SHARED-DBF integration point and the SPAWN
idiom for non-blocking server startup. Builds cleanly under
the examples_build sweep (now 66/72; was 65/71).
* CLAUDE.md — the "어떤 파일이든 수정한 후" mandatory test list
goes from 3 gates → 6:
1. go test ./...
2. FiveSql2 SQL:1999 43/43
3. Harbour compat 56/56
4. std.ch 17/17 (added)
5. FRB 7/7 (added)
6. pgserver integration 6/6 (added — psql required)
Aligns the rule-of-thumb with reality. The five suites already
ran on every audit-era commit; pgserver/run.sh is new in
Phases 3-6 and now joins them.
This completes the v1.0 PostgreSQL-wire frontend. End-to-end
checklist:
Phase 1: per-session state isolation [93cf5c8]
Phase 2: SimpleQuery wire MVP [d98f5e17083297]
Phase 3: DML + transactions [a556764]
Phase 4: Extended Protocol (Parse/Bind/Exec) [8472928]
Phase 5: password + MD5 auth [90eafcf]
Phase 6: TLS + IP allowlist [3b2dd36]
Phase 7: example + docs [this commit]
Open follow-ups (Phase 7.x):
- hbrdd workarea per-thread isolation (audit Top-Risk #2):
≥3 concurrent connections doing in-flight INSERT/SELECT in
their own transactions can race at the workarea layer. Fix
is a separate workstream against hbrtl/database.go +
hbrdd/dbf/. Documented limitation in tests/pgserver/run.sh.
- SCRAM-SHA-256 auth (Phase 5.1).
- pg_catalog shim for BI-tool introspection (Phase 1.1+ of the
original audit plan).
- Binary parameter format for NUMERIC/TIMESTAMP (Phase 4.1).
All gates green:
go test ./... ✓
FiveSql2 SQL:1999 43/43 ✓
Harbour compat 56/56 ✓
std.ch 17/17 ✓
FRB 7/7 ✓
examples 66/72 ✓ (+1 from new pgserver_demo)
pgserver integration 6/6 ✓

All 3 remaining known constraints resolved. CLAUDE.md now shows zero.
1. CDX compound index WRITE support (was read-only)
New file: hbrdd/cdx/build.go (~400 LOC)
- CreateOrAddTag() builds Harbour-compatible CDX files
- Bit-packed leaf pages (RecBits/DupBits/TrlBits compression)
- Interior nodes with big-endian RecNo/ChildPage
- Compound root directory (structural B-tree of tag names)
- Append-safe: preserves existing tags when adding new ones
- Linked leaf pages (LeftPtr/RightPtr for sequential scan)
Pipeline: INDEX ON expr TAG tagname TO file
- ast.IndexCmd gains TagName field
- Parser captures TAG name (was discarded)
- gengo passes TagName to OrderCreateParams
- indexer.go routes to cdx.CreateOrAddTag when TAG specified
Verified: 3 tags (BYNAME/BYCITY/BYAGE), OrdSetFocus by name,
SEEK, GoTop/GoBottom, close+reopen with SET INDEX TO
2. {||} empty code block parsing in function arguments
Parser's parseArrayOrBlock() called parseExpr() unconditionally
after closing |, failing when body was empty ({||}).
Fix: check for RBRACE after closing | and emit NIL literal body.
{=>} empty hash already worked.
3. Semicolon IF...ENDIF — already worked (removed from constraints)
Tests:
go test ./... 14 packages ALL PASS
FiveSql2 43/43 100%
compat_harbour 51/51
