Changelog category (leave one):

  • Improvement

Changelog entry (a user-readable short description of the changes that goes into CHANGELOG.md):

Enable the impersonate feature by default (see EXECUTE AS target_user)

Special privilege GRANT IMPERSONATE is needed in order to use this feature.

For example:

GRANT IMPERSONATE ON target_user TO user1

-- login as user1

EXECUTE AS target_user SELECT currentUser(), authenticatedUser(); -- outputs "target_user    user1"

Version info

  • Merged into: 26.3.1.18
