Add apply-count parameter

[alex-richman-onesignal]

• Add a new apply-count command line parameter to allow tuning of the REDO apply_count variable.
• Check on startup that switch_threshold is not greater or equal to apply_count, which would cause REDO to stop after the first apply_log call (fwiw this bug also exists in 1.5.0, since switch_threshold parameter was added but was not checked against the default APPLY_COUNT of 1000).
• Tuning apply_count might be useful for improving REDO performance on tables with small tuples that receive lots of updates.
• Fixes Validate switch_threshold parameter is not greater than or equal to APPLY_COUNT #393

Thanks! No objections from my side.

Could you add documentation and tests like here: https://github.com/reorg/pg_repack/pull/347/files#diff-1b3cd3a9c0b8b485f72c559854e6db0705069ce3e995fa25972825d9dcae359a.

Agree with Artur. A test would be nice to have. Otherwise it's a good addition.

[alex-richman-onesignal]

Thanks both, added a few tests and a doc line.

Thanks for the fix. I'm merging the PR.

Thanks! Do you have a schedule for when the 1.5.1 release will be cut? We're interested in this and the fix from #375 but running non-official releases is a little more challenging for us.

AFAIK we don't have a release schedule. We could make a release after accumulating few more fixes.
