# -DSQLITE_DEFAULT_PAGE_SIZE=32768 and SQLITE_MAX_DEFAULT_PAGE_SIZE=32768
# increases the page size from 1k, see bug 416330.  It must be kept in sync with
# the value of PREF_TS_PAGESIZE_DEFAULT in mozStorageService.cpp.  The value can
# be overridden on a per-platform basis through the use of the PREF_TS_PAGESIZE
# hidden preference.  If that preference is missing or invalid then this value
# will be used.
# -DSQLITE_MAX_SCHEMA_RETRY increases the times SQLite may try to reparse
# statements when the schema changes. This is important when supporting lots of
# concurrent connections, especially when they use shared cache.
# Note: Be sure to update the configure.in checks when these change!
