Comment (by Raul Marin):

 In [changeset:"17542" 17542]:
 {{{
 #!CommitTicketReference repository="" revision="17542"
 Increase size of internal PROJ cache

 Creating PROJ projections is specially slow for PROJ6, so
 we want to avoid recalculating them as much as possible

 This is specially important for ST_Buffer(geography) since
 it decides the SRID, and thus the projection, dinamically
 based on the geometry position around the globe.
