Follow up to PostgreSQL: PDOException:Invalid text representation when attempting to load an entity with a string or non-scalar ID.
In comment #256 @soyarma was right, the revision id needs to be cleaned as well. I came across this issue with the webform module. The error in watchdog was:
PDOException: SQLSTATE[22018]: [Microsoft][ODBC Driver 11 for SQL Server][SQL Server]Conversion failed when converting the varchar value 'configure' to data type int.: 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], revision.[vuuid] AS [vuuid], revision.[ds_switch] AS [ds_switch], 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], base.[uuid] AS [uuid], revision.[timestamp] AS [revision_timestamp], revision.[uid] AS [revision_uid] FROM node base INNER JOIN node_revision revision ON revision.nid = base.nid AND revision.vid = :revisionId WHERE ( ([base].[nid] IN (:db_condition_placeholder_0)) ); Array ( [:db_condition_placeholder_0] => 86475 [:revisionId] => configure ) in DrupalDefaultEntityController->load() (line 198 of E:\KDN\includes\entity.inc).
Unfortunately the patch at #16 is not resolving it.
