pgsql: Remove inappropriate translation marker in getObjectIdentityPart

Remove inappropriate translation marker in getObjectIdentityParts().

Strings built by this function are not supposed to be subject to
NLS translation, but commit 6566133c5 missed that memo, so that
object identities like "membership of role %s in role %s" were
translated.
