proj4 cache corrupted by projection error ?

[strk]

Look at this session:

strk=# select ST_Transform('SRID=4326;POINT(180 -90)'::geometry, 3857);
ERROR:  transform: couldn't project point (180 -90 0): tolerance condition error (-20)
strk=# select ST_Transform('SRID=4326;POINT(180 -89.99999999999)'::geometry, 3857);
ERROR:  AddToPROJ4SRSCache: couldn't parse proj4 string: '+proj=longlat +datum=WGS84 +no_defs ': tolerance condition error

The second ERROR doesn't sound right, seems to reveal a dirtiness in proj cache. It's critical because the cache survives multiple transactions making it impossible to perform future reprojections

This actually seems to be pj_get_errno_ref() not resetting between calls to pj_init
