PostgreSQL - Full-Text Search

How can you list all languages supported by PostgreSQL's full-text search system?

AQuery pg_ts_config and filter by cfgname for language names

BQuery the pg_ts_config catalog and join with pg_ts_dict to find language names

CCheck the pg_language system catalog

DUse the command SHOW LANGUAGES;

Step-by-Step Solution

Solution:

Step 1: Understand pg_ts_config stores configurations named by language
Each configuration usually corresponds to a language, named in cfgname.
Step 2: Use simple query filtering cfgname to list languages
Querying pg_ts_config and selecting cfgname lists supported languages.
Step 3: Eliminate other options
SHOW LANGUAGES is invalid; pg_language stores procedural languages, not text search languages; joining with pg_ts_dict is unnecessary.
Final Answer:
Query pg_ts_config and filter by cfgname for language names -> Option A
Quick Check:
Languages = cfgname in pg_ts_config [OK]

Quick Trick: Languages are cfgname values in pg_ts_config [OK]
