Justin, did you have any other comment on the patch?

I'm also not a native English speaker so I'm far for writing perfect comments
myself :)

Maybe something like

/*
 * read_pattern - reads on object pattern from input
 *
 * This function will parse any valid identifier (quoted or not, qualified or
 * not), which can also includes the full signature for routines.
 * Note that this function takes special care to sanitize the detected
 * identifier (removing extraneous whitespaces or other unnecessary
 * characters).  This is necessary as most backup/restore filtering functions
 * only recognize identifiers if they are written exactly way as they are
 * regenerated.
 * Returns a pointer to next character after the found identifier, or NULL on
 * error.
