Changelog

1.1.0 — 2026-02-19

{d[key]!j} format — jsonb literal substitution: '<value>'::jsonb (strings auto-quoted, objects/arrays pass through)
{d[key]!i} format — quote_identifier substitution for safe SQL identifiers (reserved words get quoted)
_self virtual key — injects the full input JSON when {d[_self]} or {d[_self]!j} appears in template body
render() now executes children via _process — dry-run resolves child dependencies before rendering parent SQL
REST CRUD test (07-rest-crud.sql) — demonstrates dynamic UPDATE with _self!j + jsonb_populate_record

validate() orphan check now correctly scopes to fragments (cmd IS NULL) only

C-based {d[key]} / {d[key]!r} renderer (_c_render)
SPI plan caching with per-template opt-in (cached column + fsql.cache_plans GUC)
_c_execute(sql, params, use_cache) — SPI execution with optional plan caching
clear_cache() — free all cached prepared plans
Recursive template engine (_process) with 6 cmd types: exec, ref, if, exec_tpl, map, NULL
Public API: run(), render(), tree(), explain(), validate(), depends_on()
Safe parameterized execution via fsql.params type catalog
Legacy alias support (exejson, templ, json, exejsontp)
Migration path from data_algorithms schema
Full test suite (7 test files)
