postgis install -- superfluous commit

[robe]

I think we have an extra commit in our postgis.sql. I saw some error flying by before but wasn't paying attention.

When installing against PostgreSQL 8.5 (since my regress is giving weird errors)

psql: FATAL:  parameter "port" cannot be changed without restarting the server
Creating spatial db postgis_reg
createdb: could not connect to database postgres: FATAL:  parameter "port" canno
t be changed without restarting the server

I decided to step thru the install to make sure it installs. -- I just noticed it.

There is a commit being generated right after ST_Intersection COMMIT;

So our install is not completely wrapped in a transaction. The last COMMIT; after ST_MinimumBoundingCircle gives a

psql:postgis.sql:7710: WARNING: there is no transaction in progress
