.install file: Cannot modify header information

The .install files for pgapi and it's sub-modules contain blank lines after the closing "?>" php tag. This results in php errors like:

Cannot modify header information - headers already sent by (output started at /home/rcourtna/workspace/drupal/sites/all/modules/pgapi/pgapi.install:52) in /home/rcourtna/workspace/drupal/includes/common.inc on line 319.

(See "PHP Code Tags" section of http://drupal.org/coding-standards).

The attached patch removes the closing php tags from all .install files.
