Commit d85ce012f9 has added some new error handling code to
date_trunc() of timestamp, timestamptz, and interval with infinite
values.
However, the new test cases added by that commit did not actually test
all of the new code, missing coverage for the following cases:
1) For timestamp without time zone:
1-1) infinite value with valid unit
1-2) infinite value with unsupported unit
1-3) finite value with unsupported unit, for a code path older than
d85ce012f9.
2) For timestamp with time zone, without a time zone specified for the
truncation:
2-1) infinite value with valid unit
2-2) infinite value with unsupported unit
2-3) finite value with unsupported unit, for a code path older than
d85ce012f9.
3) For timestamp with time zone, with a time zone specified for the
truncation:
3-1) infinite value with valid unit.
3-2) infinite value with unsupported unit.
This commit also provides coverage for the bug fixed in 2242b26ce4,
through cases 2-1) and 3-1), when using an infinite value with a valid
unit, with[out] the optional time zone parameter used for the
truncation.
