PostgreSQL 9.6. I just found both of these commands in a flyway migration, right next to each other. I feel like they are probably redundant but how do these statements differ? Is there a reason to use both? Apologies if this is a duplicate; I couldn't find an answer.

ALTER DATABASEwill change thesearch_pathfor every new connection to that database. The change however does not affect current connections - including the one that ran theALTER DATABASE. Theset search_paththen changes the path also for the current connection so that it has the same value as the default path.
