test_custom_stats: Test module for custom cumulative statistics
This test module acts as a replacement that existed prior to
d52c24b0f808 in the test module injection_points. It uses a more
flexible structure than its ancestor:
- Two libraries are built, one for fixed-sized stats and one for

A race condition could cause a newly created replication slot to become
invalidated between WAL reservation and a checkpoint.
Previously, if the required WAL was removed, we retried the reservation
process. However, the slot could still be

injection_points: Remove portions related to custom pgstats
The test module injection_points has been used as a landing spot to
provide coverage for the custom pgstats APIs, for both fixed-sized and
variable-sized stats kinds. Some recent work related to pgstats is
proving that this structure mak
Improve error messages of input functions for pg_dependencies and pg_ndistinct
The error details updated in this commit can be reached in the
regression tests. They did not follow the project style, and they
should be written them as full sentences.
Some of the errors are switched to use an elog
ecpg: refactor to eliminate cast-away-const in find_variable().
find_variable() and its subroutines transiently scribble on the
passed-in "name" string, even though we've declared that "const".
The string is in fact temporary, so this is not very harmful,
but it's confusing and will produce compil
Revise APIs for pushJsonbValue() and associated routines.
Instead of passing "JsonbParseState **" to pushJsonbValue(),
pass a pointer to a JsonbInState, which will contain the
parseState stack pointer as well as other useful fields.
Also, instead of returning a JsonbValue pointer that is often

Remove fundamentally-redundant processing in jsonb_agg() et al.
The various variants of jsonb_agg() operate as follows,
for each aggregate input value:
1. Build a JsonbValue tree representation of the input value.
2. Flatten the JsonbValue tree into a Jsonb in on-disk format.
3. Iterate through t
Add a macro for the declared typlen of type timetz.
pg_type.typlen says 12 for the size of timetz, but sizeof(TimeTzADT)
will be 16 on most platforms due to alignment padding. Using the
sizeof number is no problem for usages such as palloc'ing a result

Micro-optimize datatype conversions in datum_to_jsonb_internal.
The general case for converting to a JSONB numeric value is to run the
source datatype's output function and then numeric_in, but we can do
substantially better than that for integer and numeric source values.
