pg_liquid
pg_liquid is a PostgreSQL extension that maps the LIquid blog language and
data model onto native PostgreSQL storage and execution.
It ships:
liquid.query(program text)liquid.query_as(principal text, program text)liquid.read_as(principal text, program text)- row normalizer management functions for projecting relational rows into LIquid compounds
Supported LIquid program features include:
%comments.-terminated assertions and rule definitions- one terminal
?query Edge(...)- named compounds via
Type@(cid=..., role=...) - query-local recursive rules
- CLS-aware reads through
liquid.read_as(...)andliquid.query_as(...)
Version
This PGXN package is version 0.1.0.
Build And Install
Build and install against the target PostgreSQL instance:
cd libs/pg_liquid
make
make install
Then create the extension in the target database:
create extension pg_liquid;
Upgrade
The shipped upgrade path covers the legacy internal versions 1.0.0,
1.1.0, and 1.2.0 to the public release 0.1.0:
alter extension pg_liquid update to '0.1.0';
Alias scripts are also included for the legacy non-semver version names 1.0,
1.1, and 1.2.
Validation
Useful local checks:
make -C libs/pg_liquid package-check
make -C libs/pg_liquid installcheck
make -C libs/pg_liquid bench-check
make -C libs/pg_liquid pgxn-package
package-check validates META.json, the control file, and the referenced SQL
install script. pgxn-package builds a release tarball under release/.
