FAQPage Schema

How do I build and test a PostgreSQL C extension locally?▼

Building and testing a PostgreSQL C extension locally requires a Rust toolchain, a C compiler, and PostgreSQL server development headers to compile a cdylib and link it with a local PostgreSQL instance for verification.

How do I implement parser callbacks for a PostgreSQL text search extension?▼

Implementing parser callbacks for PostgreSQL text search requires authoring startfunc, gettoken, and endfunc functions to integrate FtsTokenizer lexemes directly into a tsvector.

Do I need PostgreSQL server development headers to build a C extension with Rust?▼

Yes, building a PostgreSQL C extension with Rust requires PostgreSQL server development headers, a Rust toolchain with cargo, and a C compiler to successfully build and link the cdylib.

How do I create a control file and SQL install script for a PostgreSQL extension?▼

Creating a PostgreSQL extension involves authoring a kham_pg.control file alongside SQL install scripts to register the extension and wire FtsTokenizer lexemes into the database.

Why does my PostgreSQL extension fail to export symbols during local development?▼

Symbol export issues during PostgreSQL extension development typically occur when the cdylib fails to correctly link with kham-core, requiring debugging of the build configuration and compiler flags.

What is the best way to integrate Thai text search into PostgreSQL?▼

Integrating Thai text search into PostgreSQL is achieved by building a custom C extension that uses kham-core to parse Thai text and map FtsTokenizer lexemes into a tsvector for full-text search.
