WAIT FOR LSN lsn [ TIMEOUT timeout ] New clause pospones transaction start till given lsn is applied on standby. This clause allows user be sure, that changes previously made on primary would be visible on standby. New shared memory struct is used to track awaited lsn per backend.

Regression tests for recovery and replication
=============================================

This directory contains a test suite for recovery and replication.

Running the tests
=================

NOTE: You must have given the --enable-tap-tests argument to configure.
Also, to use "make installcheck", you must have built and installed
contrib/test_decoding in addition to the core code.

Run
    make check
or
    make installcheck
You can use "make installcheck" if you previously did "make install".
In that case, the code in the installation tree is tested.  With
"make check", a temporary installation tree is built from the current
sources and then tested.

Either way, this test initializes, starts, and stops several test Postgres
clusters.
