Install fails on Postgres 8.1

Installation is failing for me on Postgres 8.1

It's throwing the following error on installation:

* warning: pg_query() [function.pg-query]: Query failed: ERROR: syntax error at or near "(" at character 136 in /home/mark/domains/dev/public_html/drupal/includes/database.pgsql.inc on line 125.
* user warning: query: CREATE TABLE node_import_mappings ( "type" VARCHAR(16) NOT NULL DEFAULT '', csv_headers TEXT NOT NULL, mapping TEXT NOT NULL, KEY type (type) ); in /home/mark/domains/dev/public_html/drupal/includes/database.pgsql.inc on line 144.
* The creation of node_import database tables has failed. Check the README.txt file in the modules/node_import directory on instructions to create the table manually.

The README.txt doesn't seem to contain manual instructions.

However, it appears to work if you make the following changes in node_import.install:

lines 17-22:
$ret = db_query("CREATE TABLE {node_import_mappings} ( ".
"\"type\" VARCHAR(16) NOT NULL DEFAULT '', ".
"csv_headers TEXT NOT NULL, ".
"mapping TEXT NOT NULL, ".
"PRIMARY KEY (\"type\") ".
");");

lines 43-48:
$items[] = update_sql("CREATE TABLE {node_import_mappings} ( ".
"type VARCHAR(16) NOT NULL DEFAULT '', ".
"csv_headers TEXT NOT NULL, ".
"mapping TEXT NOT NULL, ".
"KEY type (type) ".
") /*!40100 DEFAULT CHARACTER SET utf8 */;");

Has anyone else dealt with this issue? Thanks.
