Tom Lane e9f42d529f Clean up/tighten up coercibility checks in opr_sanity regression test. 
With the removal of the old abstime type, there are no longer any cases
in this test where we need to use the weaker castcontext-ignoring form
of binary coercibility check.  (The other major source of such headaches,
apparently-incompatible hash functions, is now hashvalidate()'s problem
not this test script's problem.)  Hence, just use binary_coercible()
everywhere, and remove the comments explaining why we don't do so ---
which were broken anyway by cda6a8d01.

I left physically_coercible() in place but renamed it to better
match what it's actually testing, and added some comments.

Also, in test queries that have an assumption about the maximum number
of function arguments they need to handle, add a clause to make them fail
if someday there's a relevant function with more arguments.  Otherwise
we're likely not to notice that we need to extend the queries.

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/.
