#3460: Upgrade to 2.2 doesn't adjust size of pgis_abs type
---------------------+---------------------------
 Reporter:  dbaston  |      Owner:  pramsey
     Type:  defect   |     Status:  new
 Priority:  high     |  Milestone:  PostGIS 2.2.2
Component:  postgis  |    Version:  2.2.x
 Keywords:           |
---------------------+---------------------------
 The size of the {{{pgis_abs}}} type was changed from 8 bytes to 16 bytes
 in 2.2.0.  It doesn't appear that the upgrade procedure handles this, so
 if you upgrade to 2.2.x from a previous version, Postgres would still
 think the size is 8 bytes.

 I haven't been able to show this, because I can't actually perform an
 upgrade from 2.1.x to more recent versions due to #3429.  But this seems
 like it would explain the following issue reported to postgis-users:
