This commit continues the code improvements started by commit 12788ae49e19. 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. Author: Fabien Coelho, Álvaro Herrera Reviewed-by: Kirk Jamison Discussion: https://postgr.es/m/alpine.DEB.2.21.1808111104320.1705@lancre
