Reduce number of INSERT statements

[strk]

I was just annoyed by the many INSERT reports printed back
upon running make check. Not sure this is the actual source
or this is a file generated by sqitch or something, let me know :)

I would reduce more INSERT statements in other files, but if they are generated it'd be a waste of time to tweak them so please let me know (@dwsilk ?).

Many such "offending" files are under db/tests/testdata/db:

db/tests/testdata/db$ grep -ic INSERT *
admin_bdys.sql:8
aerial_lds.sql:2
buildings_bulk_load.sql:494
buildings_common.sql:2
buildings_lds.sql:143
buildings_reference.sql:21
buildings.sql:292
update_sequences.sql:0

That will certainly clean things up quite a bit :-)

The only thing I can think of is that this script might also need to be adjusted to align with this change: https://github.com/linz/nz-buildings/blob/master/db/scripts/dump_schema.sh

Also I can now see that our GitHub Actions checks don't work on PRs from forks. We should fix that too.

@dwsilk is that script used to generate those files ? If so... should those files NOT be in the git repository at all ?
