Amit Langote 847ee701bd SQL/JSON: Some fixes to JsonBehavior expression casting 1. Remove the special case handling when casting the JsonBehavior expressions to types with typmod, like `86d33987` did for the casting of SQL/JSON constructor functions. 2. Fix casting for fixed-length character and bit string types by using assignment-level casts. This is again similar to what `86d33987` did, but for ON ERROR / EMPTY expressions. 3. Use runtime coercion for the boolean ON ERROR constants so that using fixed-length character string types, for example, for an EXISTS column doesn't cause a "value too long for type character(n)" when the parser tries to coerce the default ON ERROR value "false" to that type, that is, even when clause is not specified. 4. Simplify the conditions of when to use runtime coercion vs creating the cast expression in the parser itself. jsonb-valued expressions are now always coerced at runtime and boolean expressions too if the target type is a string type for the reasons mentioned above. New tests are from a patch that Jian He posted. Outputs of some existing tests change because the coercion now happens at runtime instead of at parse time.

PostgreSQL tests
================

This directory contains a variety of test infrastructure as well as some of the
tests in PostgreSQL. Not all tests are here -- in particular, there are more in
individual contrib/ modules and in src/bin.

Not all these tests get run by "make check". Check src/test/Makefile to see
which tests get run automatically.

authentication/
  Tests for authentication (but see also below)

examples/
  Demonstration programs for libpq that double as regression tests via
  "make check"

isolation/
  Tests for concurrent behavior at the SQL level

kerberos/
  Tests for Kerberos/GSSAPI authentication and encryption

ldap/
  Tests for LDAP-based authentication

locale/
  Sanity checks for locale data, encodings, etc

mb/
  Tests for multibyte encoding (UTF-8) support

modules/
  Extensions used only or mainly for test purposes, generally not suitable
  for installing in production databases

perl/
  Infrastructure for Perl-based TAP tests

recovery/
  Test suite for recovery and replication

regress/
  PostgreSQL's main regression test suite, pg_regress

ssl/
  Tests to exercise and verify SSL certificate handling

subscription/
  Tests for logical replication
