+# PostgreSQL formula which supports extensions.
+#
+# - This formula is not keg-only, so it can be linked into the Homebrew prefix.
+# - This formula loads extensions from `$HOMEBREW_PREFIX/share/postgresql@16`
+#   and `$HOMEBREW_PREFIX/lib/postgresql@16`, instead of in the keg directory.
+#
+#   This makes it possible to install extensions like PostGIS for PostgreSQL
+#   16, by linking them into the same directories.
+#
+#
+# Generated with:
+#     brew tap --force homebrew/homebrew-core
+#     brew extract homebrew/homebrew-core/postgresql@16 MercuryTechnologies/homebrew-tap
