/*
** This function queries the database for the names of the columns of table
** zThis, in schema zDb. It is expected that the table has nCol columns. If
** not, SQLITE_SCHEMA is returned and none of the output variables are
** populated.
**
** Otherwise, if they are not NULL, variable *pnCol is set to the number
** of columns in the database table and variable *pzTab is set to point to a
** nul-terminated copy of the table name. *pazCol (if not NULL) is set to
** point to an array of pointers to column names. And *pabPK (again, if not
** NULL) is set to point to an array of booleans - true if the corresponding
** column is part of the primary key.
**
** For example, if the table is declared as:
**
**     CREATE TABLE tbl1(w, x, y, z, PRIMARY KEY(w, z));
**
** Then the four output variables are populated as follows:
**
**     *pnCol  = 4
**     *pzTab  = "tbl1"
**     *pazCol = {"w", "x", "y", "z"}
**     *pabPK  = {1, 0, 0, 1}
**
** All returned buffers are part of the same single allocation, which must
** be freed using sqlite3_free() by the caller. If pazCol was not NULL, then
** pointer *pazCol should be freed to release all memory. Otherwise, pointer
** *pabPK. It is illegal for both pazCol and pabPK to be NULL.
