DatabaseSchemaObjectExistsException: Table salesforce_prematch already exists. in DatabaseSchema->createTable() (line 630 of /var/www/drupal-7/includes/database/schema.inc).

'nicholasThompson' is saying in his comment
"It seems hook_schema() now gets called in install and uninstall automatically"

If I am commenting hook_install then this problem is not comming.

/**
 * Implementation of hook_install().
 */
/*function sf_prematch_install() {
  drupal_install_schema('sf_prematch');
}*/
