That says the build gave you the necessary MySQL support...

Can you confirm that this is indeed on line 823, is in the 'main'
section, i.e. before any acl's or router/transport sets appear, and is
the *only* such call in the entire config file?
N.B. Line 823 seems rather too high a line-count for the position of the
'hide mysql..' call. Unless you've left all the comments in-place, this
is more often in the first 10 to 50 lines.
Further, the format you have used may not be quite correct. Do you need
a username as well as a password, for example?
PostgreSQL is *slightly* different from MYSQL, but ours looks like this:
There are no "<" or ">" in the original, the parenthesis matter, and the
<socketfilename> is not an 'ordinary' file, but something akin to:
/tmp/.s.PGSQL.5432
You can also use an IP instead of a unix socket, pros and cons discussed
elsewhere, but if so, a specific IP would be my preference, AND NOT
'localhost', even if you have to alias-up a bespoke IP just for MySQL
and the MTA to use.
In general IP is best if/as/when the DB is not on the same box as the
MTA, and the communication is on an internal-only LAN ELSE otherwise
secured (SSL tunnel, matching PEM certs, etc.)
Sockets are generally better all-around for same-box use.
