Comment (by c0ntax):

 The following in get_col_length() also seems to make the same assumption
 that running get_table_charset() will ensure that col_meta is populated:

 {{{#!php
                 if ( empty( $this->col_meta[ $tablekey ] ) ) {
                         // This primes column information for us.
                         $table_charset = $this->get_table_charset( $table
 );
                         if ( is_wp_error( $table_charset ) ) {
                                 return $table_charset;
                         }
                 }

                 if ( empty( $this->col_meta[ $tablekey ][ $columnkey ] ) )
 {
                         return false;
                 }
 }}}
