 In contradiction with what's written here :
 http://www.postgis.org/documentation/manual-1.4/ch02.html#id2478443

 Postgis doesn's seem to work with postgresql 8.1. I had this error while
 trying to load it :
 psql:../postgresql-8.1.18.bin/share/contrib/postgis.sql:53: ERROR:  could
 not load library
 "/home/marc/temp/postgresql-8.1.18.bin/lib/postgis-1.4.so":
 /home/marc/temp/postgresql-8.1.18.bin/lib/postgis-1.4.so: undefined
 symbol: ARR_NULLBITMAP

 I traced back the error to the macro ARR_NULLBITMAP being only available
 since PostgreSQL 8.2. Postgis will compile and link with 8.1, but will
 fail at install.

 Not a big problem for me, but a user in our forum suffered a few days from
 it, till I looked into it.
