Alvaro Herrera 3bac77c48f Rework the pgbench state machine code for clarity 
This commit continues the code improvements started by commit
12788ae49e.  With this commit, state machine transitions are better
contained in the routine that was called doCustom() and is now called
advanceConnectionState -- the resulting code is easier to reason about,
since there are no state changes occuring in the outer layer.

This change is prompted by future patches to add more features to
pgbench, which will need to effect some more surgery to this code.

Fabien's original had all the machine state changes inside one routine,
but I (Álvaro) thought that a subroutine to handle command execution is
more straightforward to review, so this commit does not match Fabien's
submission closely.  If something is broken, it's probably my fault.

PostgreSQL Database Management System
=====================================

This directory contains the source code distribution of the PostgreSQL
database management system.

PostgreSQL is an advanced object-relational database management system
that supports an extended subset of the SQL standard, including
transactions, foreign keys, subqueries, triggers, user-defined types
and functions.  This distribution also contains C language bindings.

PostgreSQL has many language interfaces, many of which are listed here:

	https://www.postgresql.org/download

See the file INSTALL for instructions on how to build and install
PostgreSQL.  That file also lists supported operating systems and
hardware platforms and contains information regarding any other
software packages that are required to build or run the PostgreSQL
system.  Copyright and license information can be found in the
file COPYRIGHT.  A comprehensive documentation set is included in this
distribution; it can be read as described in the installation
instructions.

The latest version of this software may be obtained at
https://www.postgresql.org/download/.  For more information look at our
web site located at https://www.postgresql.org/.
