TIDStore is a data structure designed to efficiently store large sets of TIDs. For TID storage, it employs a radix tree, where the key is a block number, and the value is a bitmap representing offset numbers. The TIDStore can be created on a DSA area and used by multiple backend processes simultaneously. There are potential future users such as tidbitmap.c, though it's very likely the interface will need to evolve as we come to understand the needs of different kinds of users. For example, we can support updating the offset bitmap of existing values. Currently, the TIDStore is not used for anything yet, aside from the test code. But an upcoming patch will use it. This includes a unit test module, in src/test/modules/test_tidstore. Co-authored-by: John Naylor Discussion: https://postgr.es/m/CAD21AoAfOZvmfR0j8VmZorZjL7RhTiQdVttNuC4W-Shdc2a-AA%40mail.gmail.com |

PostgreSQL tests ================ This directory contains a variety of test infrastructure as well as some of the tests in PostgreSQL. Not all tests are here -- in particular, there are more in individual contrib/ modules and in src/bin. Not all these tests get run by "make check". Check src/test/Makefile to see which tests get run automatically. authentication/ Tests for authentication (but see also below) examples/ Demonstration programs for libpq that double as regression tests via "make check" isolation/ Tests for concurrent behavior at the SQL level kerberos/ Tests for Kerberos/GSSAPI authentication and encryption ldap/ Tests for LDAP-based authentication locale/ Sanity checks for locale data, encodings, etc mb/ Tests for multibyte encoding (UTF-8) support modules/ Extensions used only or mainly for test purposes, generally not suitable for installing in production databases perl/ Infrastructure for Perl-based TAP tests recovery/ Test suite for recovery and replication regress/ PostgreSQL's main regression test suite, pg_regress ssl/ Tests to exercise and verify SSL certificate handling subscription/ Tests for logical replication
