Problem with node/add Fatal Error- Mysql to Postgresql

This isn't sounding like an issue related to this module.

Can you post more detail about your error? The error.log or entries from Watchdog?

Also, steps to replicate this would be good. If we can't replicate it we can't fix it.

I'm facing the same error. The migration MySQL > PostgreSQL went smooth but after changing the default DB to the new populated PG, on node/add page I'm getting:

PDOException: SQLSTATE[22P02]: Invalid text representation: 7 ERROR: invalid input syntax for integer: "add" LINE 5: WHERE (base.nid IN ('add')) ^: SELECT revision.vid AS vid, base.uid AS uid, revision.title AS title, revision.log AS log, revision.status AS status, revision.comment AS comment, revision.promote AS promote, revision.sticky AS sticky, base.nid AS nid, base.type AS type, base.language AS language, base.created AS created, base.changed AS changed, base.tnid AS tnid, base.translate AS translate, revision.timestamp AS revision_timestamp, revision.uid AS revision_uid FROM {node} base INNER JOIN {node_revision} revision ON revision.vid = base.vid WHERE (base.nid IN (:db_condition_placeholder_0)) ; Array ( [:db_condition_placeholder_0] => add ) in EntityCacheControllerHelper::entityCacheLoad() (line 100 of sites/all/modules/entitycache/entitycache.module).

It seems to me that Drupal doesn't select the best route for node/add like he's trying to execute the callback corresponding to route node/%node.

@pineiden, do you have some fresh feedback on that?

This duplicates #1851398: PDOException:Invalid text representation when attempting to load an entity with a string ID and the patch posted there is fixing the issue.
