Currently we cannot install Age to shared_preload_libraries if
pg_cron is installed.

To prevent following error we must bail out early.
postgres=# set backtrace_functions to 'get_namespace_oid';
SET
postgres=# create extension pg_cron ;

- start_index marks where property fields begin. For edges, it's 4.
  If start_index >= total_fields, create empty properties; otherwise,
  parse the properties.
- Fixed some operator signatures in .sql
- Added support for PG operators in cypher. Some
  hardcoded operators are removed, since they are
  now covered by the general operator handling.
- Added full typecast syntax that allows for type
  modifiers.
- These changes also improve interoperability with
  other extensions, as reflected in the regression
  tests.
- Added a new function to check if graph_oid exists.
- This was also failing CI. The issue is described here gradle/gradle#33950
This PR fixes the issue of some string functions returning NULL
instead of the empty string.

The string functions affected and corrected are -

reverse, toupper, tolower, rtrim, ltrim, trim, right, left, substring,
and replace.

Added additional regression tests. Corrected previous tests.
