CREATE TABLE WORK_QUEUE ... twice?

[Julian Foad]

subversion/libsvn_wc/wc-metadata.sql contains CREATE TABLE WORK_QUEUE
(...) twice, the same each time. Intentional?

Here is that section of the file in full:
[[[
CREATE TABLE WORK_QUEUE (
  /* Work items are identified by this value.  */
  id  INTEGER PRIMARY KEY AUTOINCREMENT,

  /* A serialized skel specifying the work item.  */
  work  BLOB NOT NULL
  );


/* ------------------------------------------------------------------------- */

CREATE TABLE WC_LOCK (
  /* specifies the location of this node in the local filesystem */
  wc_id  INTEGER NOT NULL  REFERENCES WCROOT (id),
  local_dir_relpath  TEXT NOT NULL,

  locked_levels  INTEGER NOT NULL DEFAULT -1,

  PRIMARY KEY (wc_id, local_dir_relpath)
 );


PRAGMA user_version = 16;


/* ------------------------------------------------------------------------- */

/* Format 13 introduces the work queue, and erases a few columns from the
   original schema.  */
-- STMT_UPGRADE_TO_13

CREATE TABLE WORK_QUEUE (
  /* Work items are identified by this value.  */
  id  INTEGER PRIMARY KEY AUTOINCREMENT,

  /* A serialized skel specifying the work item.  */
  work  BLOB NOT NULL
  );

/* The contents of dav_cache are suspect in format 12, so it is best to just
   erase anything there.  */
UPDATE BASE_NODE SET incomplete_children=null, dav_cache=null;

PRAGMA user_version = 13;
]]]
