// immutable=Boolean
// The immutable parameter is a boolean query parameter that indicates
// that the database file is stored on read-only media. When immutable is set,
// SQLite assumes that the database file cannot be changed,
// even by a process with higher privilege,
// and so the database is opened read-only and all locking and change detection is disabled.
// Caution: Setting the immutable property on a database file that
// does in fact change can result in incorrect query results and/or SQLITE_CORRUPT errors.
//
// go-sqlite3 adds the following query parameters to those used by SQLite:
// _loc=XXX
// Specify location of time format. It's possible to specify "auto".
// _busy_timeout=XXX
// Specify value for sqlite3_busy_timeout.
//
// _mutex=XXX
// Specify mutex mode. XXX can be "no", "full".
//
// _txlock=XXX
// Specify locking behavior for transactions. XXX can be "immediate",
// "deferred", "exclusive".
// _foreign_keys=X
// Enable or disable enforcement of foreign keys. X can be 1 or 0.
// _recursive_triggers=X
// Enable or disable recursive triggers. X can be 1 or 0.
//
// _auto_vacuum=X | _vacuum=X
// 0 | none - Auto Vacuum disabled
// 1 | full - Auto Vacuum FULL
// 2 | incremental - Auto Vacuum Incremental

//
// _case_sensitive_like=Boolean | _cslike=Boolean
// https://www.sqlite.org/pragma.html#pragma_case_sensitive_like
// Default or disabled the LIKE operation is case-insensitive.
// When enabling this options behaviour of LIKE will become case-sensitive.
//
// _defer_foreign_keys=Boolean | _defer_fk=Boolean
// Defer Foreign Keys until outermost transaction is committed.
//
// _foreign_keys=Boolean | _fk=Boolean
// Enable or disable enforcement of foreign keys.
//
// _ignore_check_constraints=Boolean
// This pragma enables or disables the enforcement of CHECK constraints.

//
// _journal_mode=MODE | _journal=MODE
// Set journal mode for the databases associated with the current connection.
// https://www.sqlite.org/pragma.html#pragma_journal_mode
//
// _locking_mode=X | _locking=X
// Sets the database connection locking-mode.
// The locking-mode is either NORMAL or EXCLUSIVE.

//
// _query_only=Boolean
// The query_only pragma prevents all changes to database files when enabled.
