Apply time column precision on assignment.
PR #20317 changed the behavior of datetime columns so that when they have a specified precision then on assignment the value is rounded to that precision. This behavior is now applied to time columns as well.
Fixes #30301.
Andrew White
-
Normalize time column values for SQLite database.
For legacy reasons, time columns in SQLite are stored as full datetimes because until #24542 the quoting for time columns didn't remove the date component. To ensure that values are consistent we now normalize the date component to 2001-01-01 on reading and writing.
Andrew White
-
Ensure that the date component is removed when quoting times.
PR #24542 altered the quoting for time columns so that the date component was removed however it only removed it when it was 2001-01-01. Now the date component is removed irrespective of what the date is.

PostgreSQL: Fix
db:structure:load
silent failure on SQL error.The command line flag
-v ON_ERROR_STOP=1
should be used when invokingpsql
to make sure errors are not suppressed.Example:
psql -v ON_ERROR_STOP=1 -q -f awesome-file.sql my-app-db
Fixes #23818.
