Dear sir,
Is there a way to turn off the Pager subsystem of SQLIte application - that is,
not have to deal with declarations and definitions of the functions ** that
make
up the Pager sub-system API?

As examples:
/* Open and close a Pager connection. */
SQLITE_PRIVATE int sqlite3PagerOpen(
sqlite3_vfs*,
Pager **ppPager,
const char*,
int,
int,
int,
void(*)(DbPage*)
);
SQLITE_PRIVATE int sqlite3PagerClose(Pager *pPager);
SQLITE_PRIVATE int sqlite3PagerReadFileheader(Pager*, int, unsigned char*);
/* Functions used to configure a Pager object. */
SQLITE_PRIVATE void sqlite3PagerSetBusyhandler(Pager*, int(*)(void *), void *);
SQLITE_PRIVATE int sqlite3PagerSetPagesize(Pager*, u32*, int);
