    <glossterm>Buffer Access Strategy</glossterm>

-     Some operations will access a large number of pages at a time. In order to
-     avoid using all of <varname>shared_buffers</varname> and evicting blocks
-     from buffers in use by other workloads, some operations employ a
-     <varname>Buffer Access Strategy</varname>. A <varname>Buffer Access
-     Strategy</varname> sets up references to a limited number of
-     <varname>shared_buffers</varname> and reuses them circularly. If the
-     operation dirties a buffer that it then must reuse, it must write out that
-     buffer and any associated WAL itself.
