'need' is a bit strong. I have never worried about pagesize in a database.
I’ve always just left it at the default for whatever platform I’m using when I
create the database. But I don’t write programs where SQLite speed is a
bottleneck.
I have previous argued for category documention for PRAGMAs: which ones are
stored in the database, which ones just tell you things, etc..
The only pragma needed anew for each connection to the database is
PRAGMA busy_timeout = milliseconds
I might argue that given what it does, this should really be saved in the
database file somewhere.
The rest
* just tell you things, have no lasting effect
* are single-use tools which change the database file in a one-time way
* are saved in the database file (e.g. journal mode = WAL, page size)
* can reasonably be different for different concurrent connections to the
database (some poll for changes, others log changes)
