[PATCH 2/2] Add the "dummy_table_am" test module
Julien Tachoires <julien@tachoires.me> — 2025-03-01T19:50:13Z
This test module is in charge of testing table AM reloptions. It's very similar to what we do in dummy_index_am as we have to exercise the exact same kind of feature. --- src/test/modules/Makefile | 1 + src/test/modules/dummy_table_am/Makefile | 20 + src/test/modules/dummy_table_am/README | 14 + .../dummy_table_am/dummy_table_am--1.0.sql | 13 + .../modules/dummy_table_am/dummy_table_am.c | 588 ++++++++++++++++++ .../dummy_table_am/dummy_table_am.control | 5 + .../dummy_table_am/expected/reloptions.out | 181 ++++++ src/test/modules/dummy_table_am/meson.build | 33 + .../modules/dummy_table_am/sql/reloptions.sql | 99 +++ src/test/modules/meson.build | 1 + 10 files changed, 955 insertions(+) create mode 100644 src/test/modules/dummy_table_am/Makefile create mode 100644 src/test/modules/dummy_table_am/README create mode 100644 src/test/modules/dummy_table_am/dummy_table_am--1.0.sql create mode 100644 src/test/modules/dummy_table_am/dummy_table_am.c create mode 100644 src/test/modules/dummy_table_am/dummy_table_am.control create mode 100644 src/test/modules/dummy_table_am/expected/reloptions.out create mode 100644 src/test/modules/dummy_table_am/meson.build create mode 100644 src/test/modules/dummy_table_am/sql/reloptions.sql diff --git a/src/test/modules/Makefile b/src/test/modules/Makefile index 4e4be3fa511..8fe2a2904d6 100644 --- a/src/test/modules/Makefile +++ b/src/test/modules/Makefile @@ -9,6 +9,7 @@ SUBDIRS = \ commit_ts \ delay_execution \ dummy_index_am \ + dummy_table_am \ dummy_seclabel \ libpq_pipeline \ oauth_validator \ diff --git a/src/test/modules/dummy_table_am/Makefile b/src/test/modules/dummy_table_am/Makefile new file mode 100644 index 00000000000..94837dff392 --- /dev/null +++ b/src/test/modules/dummy_table_am/Makefile @@ -0,0 +1,20 @@ +# src/test/modules/dummy_table_am/Makefile + +MODULES = dummy_table_am + +EXTENSION = dummy_table_am +DATA = dummy_table_am--1.0.sql +PGFILEDESC = "dummy_table_am - table access method template" + +REGRESS = reloptions + +ifdef USE_PGXS +PG_CONFIG = pg_config +PGXS := $(shell $(PG_CONFIG) --pgxs) +include $(PGXS) +else +subdir = src/test/modules/dummy_table_am +top_builddir = ../../../.. +include $(top_builddir)/src/Makefile.global +include $(top_srcdir)/contrib/contrib-global.mk +endif diff --git a/src/test/modules/dummy_table_am/README b/src/test/modules/dummy_table_am/README new file mode 100644 index 00000000000..50cf08ee3b1 --- /dev/null +++ b/src/test/modules/dummy_table_am/README @@ -0,0 +1,14 @@ +Dummy Table AM +============== + +Dummy table AM is a module for testing any facility usable by a table +access method, whose code is kept a maximum simple. + +This includes tests for all relation option types: +- boolean +- enum +- integer +- real +- strings (with and without NULL as default) + +It also includes tests related to unrecognized options. diff --git a/src/test/modules/dummy_table_am/dummy_table_am--1.0.sql b/src/test/modules/dummy_table_am/dummy_table_am--1.0.sql new file mode 100644 index 00000000000..12ad3ad174b --- /dev/null +++ b/src/test/modules/dummy_table_am/dummy_table_am--1.0.sql @@ -0,0 +1,13 @@ +/* src/test/modules/dummy_table_am/dummy_table_am--1.0.sql */ + +-- complain if script is sourced in psql, rather than via CREATE EXTENSION +\echo Use "CREATE EXTENSION dummy_table_am" to load this file. \quit + +CREATE FUNCTION dummy_table_am_handler(internal) +RETURNS table_am_handler +AS 'MODULE_PATHNAME' +LANGUAGE C;
