+  fix: the web service starts once libpq can be found.
+
+  * The web service unit waits, with wait-for-libpq, until libpq is in the
+    linker cache before it starts the service, for at most 5 minutes; the
+    service imports psycopg at start again.
+  * The package starts the web service without waiting for it.
