pg_ts_config_map
The pg_ts_config_map catalog contains entries showing which text search dictionaries should be consulted, and in what order, for each output token type of each text search configuration's parser. PostgreSQL's text search features are described at length in Chapter 12.

Column evolution matrix
Hover a cell for the column type9.0 is the coverage baseline; a column already present in the baseline is not marked as added. The matrix aligns columns by name, so a rename appears as the old column removed and a new column added.
Evolution timeline
Changes between adjacent majorsNo column-structure or description change between the covered versions.
Compare any two versions
Pick two versions to see added, removed, and retyped columns. The interactive comparison needs JavaScript; the evolution timeline reads fine without it.
