A collection of various stress tests focused on different parts of code, possibly useful for future development (e.g. when implementing changes in the same area).
-
brin-randomized- Creates BRIN indexes (different data types / index opclasses), and verifies that the query results are correct by comparing the results to seqscan. Also occasionally summarizes part of the table / whole table, does inserts etc. -
gin-tests- - Tests for evaluation of the GIN improvements. Uses queries on mailing list archives (system called "archie"). -
incremental-sort- Tests for evaluation of the incremental sort patch. -
incremental-sort-2- Tests for evaluation of the incremental sort patch. -
index-prefetching- Tests for evaluation of the index prefetch patch. -
logicalrel-ddl- Logical replication stress test with concurrent DDL. -
skip-scan- Tests for evaluation of the skip scan patch. -
stats-tests- Evaluation of estimation accuracy with different data sets and parameters (statistics target etc.). Produces gnuplot plots showing the estimated/actual cardinality.
