Tom Lane 8a37951eeb Mark built-in coercion functions as leakproof where possible. 
Making these leakproof seems helpful since (for example) if you have a
function f(int8) that is leakproof, you don't want it to effectively
become non-leakproof when you apply it to an int4 or int2 column.
But that's what happens today, since the implicit up-coercion will
not be leakproof.

Most of the coercion functions that visibly can't throw errors are
functions that convert numeric datatypes to other, wider ones.
Notable is that float4_numeric and float8_numeric can be marked
leakproof; before commit a57d312a7 they could not have been.
I also marked the functions that coerce strings to "name" as leakproof;
that's okay today because they truncate silently, but if we ever
reconsidered that behavior then they could no longer be leakproof.

I desisted from marking rtrim1() as leakproof; it appears so right now,
but the code seems a little too complex and perhaps subject to change,
since it's shared with other SQL functions.

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/.
