To increase schema security we do not want to mix our own internal
objects with user objects. Since chunks are created in the
_timescaledb_internal schema our internal functions should live in
a different dedicated schema. This patch make the necessary
adjustments for the following functions:
- to_unix_microseconds(timestamptz)
- to_timestamp(bigint)
- to_timestamp_without_timezone(bigint)
- to_date(bigint)
- to_interval(bigint)
- interval_to_usec(interval)
- time_to_internal(anyelement)
- subtract_integer_from_now(regclass, bigint)
Bump year in copyright information to 2022 and adjust same scripts
to reference NOTICE that didn't have the reference yet.
This patch also removes orphaned test/expected/utils.out.
The memory leak job pulls TSDB dev tools from bitbucket but only two
files from that repository are needed.
This commit copy the files from the `tsdb-dev-tools` repository, remove
the need to clone the repository, update the memory leak job to use
these files, and remove the two secrets containing the environment
variables `USR` and `PASSWORD`.
