I am new to postgres and do not have a complete list of executables that are expected to be present.
Is there any command or method with which we as DBAs can check for completeness of installation.
Read the documentation for the version you have installed. It includes reference pages for the various binaries that get produced.

p.s., maybe consider not including that signature for emails to a public mailing list...especially when you reply without trimming out unnecessary content. We prefer inline or bottom-posting on these lists.
