     Type:  defect         |      Status:  new          
 Priority:  medium         |   Milestone:  PostGIS 2.1.5
Component:  documentation  |     Version:  2.1.x        
 Keywords:                 |  
---------------------------+------------------------------------------------
 As noted by someone on IRC, if you upgrade PostGIS from 2.something to 2.1
 and forget to rerun the legacy.sql script (only applies if you ran it in
 first place),

 You may get:

 {{{
 Thing is, spatial queries still report this: ERROR: could not access file
 "$libdir/postgis-2.0": No such file or directory
 }}}

 I've also seen the dreaded backend error caused by two versions of PostGIS
 running in same db with same set of GUCs fighting for each other.  The
 other error (can't remember what it is), happens if postgis-2.0 is still
 present (then you have the unpleasant situation of 2 instances of PostGIS
 running)

 I'm hoping in 2.2 that we can get rid of all references to $libdir in the
 legacy scripts, but fair there may be a couple we can't get rid of.
