A tablesample count executes in two phases:
* Estimate table sizes based on reltuples.
* Based on the estimate:
  * If the table is considered 'small', execute an exact relation count.
  * Otherwise, count on a sample of the table using TABLESAMPLE.

The size of the sample is chosen in a way that we always roughly scan
the same amount of rows (see TABLESAMPLE_ROW_TARGET).

The goal is to reflect separation of concern also in specs.

The `only_protected_branches` value was being enabled by default
even though the checkbox was default off. In EE, this wasn't a
problem because there was EE-specific code to update the
entire form.
