=====================================

This module was developed to test libpq's "pipeline" mode, but it can

be used for any libpq test that requires specialized C code.

"make check" will run all the tests in the module against a temporary

server installation.

You can manually run a specific test by running:

./libpq_pipeline <name of test> [ <connection string> ]

This will not start a new server, but rather connect to the server

specified by the connection string, or your default server if you

leave that out. To discover the available test names, run:

./libpq_pipeline tests

To add a new test to this module, you need to edit libpq_pipeline.c.

Add a function to perform the test, and arrange for main() to call it

when the name of your new test is passed to the program. Don't forget

to add the name of your test to the print_test_list() function, else

the TAP test won't run it.

If the order in which Postgres protocol messages are sent is deterministic

in your test, you should arrange for the message sequence to be verified

by the TAP test. First generate a reference trace file, using a command

like:

./libpq_pipeline -t traces/mynewtest.trace mynewtest

Then add your test's name to the list in the $cmptrace definition in the

t/001_libpq_pipeline.pl file. Run "make check" a few times to verify

that the trace output actually is stable.
