`CURRENT_TIMESTAMP()` an alias for `NOW()` returns the current date and
time in the format `YYYY-MM-DD hh:mm:ss` using the session time zone.
Since we are using numeric context, the value is stored in the format
`YYYYMMDDhhmmss`. But actually we want to set a (millisecond) UNIX
timestamp here, so we need to use `UNIX_TIMESTAMP()` instead.
Initially, we planed a 1.2.0 release instead of 1.1.1 so over time, both schema
upgrade files appeared. Merge them to clean up in preparation for the 1.1.1
release.
Changes were generated using these commands:
{ echo; cat schema/mysql/upgrades/1.2.0.sql } >> schema/mysql/upgrades/1.1.1.sql
{ echo; cat schema/pgsql/upgrades/1.2.0.sql } >> schema/pgsql/upgrades/1.1.1.sql
git rm schema/mysql/upgrades/1.2.0.sql
git rm schema/pgsql/upgrades/1.2.0.sql
