The existing syntax for CREATE SERVER
CREATE [OR REPLACE] SERVER [IF NOT EXISTS] server_name
FOREIGN DATA WRAPPER wrapper_name
OPTIONS (option [, option] ...)
option:
{ HOST character-literal
| DATABASE character-literal
| USER character-literal
| PASSWORD character-literal
| SOCKET character-literal
| OWNER character-literal
| PORT numeric-literal }
With this change we have:
option:
{ HOST character-literal
| DATABASE character-literal
| USER character-literal
| PASSWORD character-literal
| SOCKET character-literal
| OWNER character-literal
| PORT numeric-literal
| PORT quoted-numerical-literal
| identifier character-literal}
We store these options as a JSON field in the mysql.servers system
table. We retain the restriction that PORT needs to be a number, but
also allow it to be a quoted number, so that SHOW CREATE SERVER can be
used for dumping. Without an accompanied implementation of SHOW CREATE
SERVER, some mysqldump tests will fail. Therefore this commit should
be immediately followed by the one implementating SHOW CREATE SERVER,
with testing covering both.
