    psql: Fix expanded aligned output
    
    When a table's columns are narrower than the record header line, the
    expanded aligned format produced misaligned output because the data
    column width was not adjusted to match the record header width, leading
    to output like:
    +-[ RECORD 1 ]-+
    | a | 10 |
    | b | 20 |
    +---+----+
    
    This commit adjusts the output so as the column width match with the
    header line, giving:
    +-[ RECORD 1 ]-+
    | a | 10       |
    | b | 20       |
    +---+----------+
