# Swaps the unique index for AlertManagement::HttpIntegration to include
# inactive integrations, making performance optimizations easier.
#
# At time of writing, gitlab.com has 0 records which would be invalidated
# by the new index. Of the ~1600 integrations, only ~100 are inactive, so the
# size of the index will not significantly change.
