Maximum Length |
|
BYTEA (binary string) |
0 < N <= 65536 |
|
CHAR(N) |
Fixed-length. Maximum length depends on character set (encoding). 0 < N * B <= 65536 where B is the maximum number of bytes for a single character. |
|
VARCHAR(N) |
Maximum length depends on character set (encoding). 0 < N * B <= 65536, where B is the maximum number of bytes for a single character. For example, for UTF-8 it is 4 bytes, so the maximum number of characters that can be stored in a (VAR)CHAR column is 65536 / 4 = 16384 |
