When checking if a branch is protected we don't need all columns of
every protected branch row, instead we only care about the names. By
using "select" here we reduce the amount of data we need to send over
the wire and load into memory.
Improvements and refactorings were made while adding role based permissions for protected tags to EE. This doesn’t backport the feature, but should improve code quality and minimize divergence.
This memorized array appears to originally come from 19c2c90cca which has a commit message of ‘fix warnings’. Without any comments on the original pull request I think we can safely get rid of it unless warnings re-appear.
