Fix client programs' handling of special characters in database and

Numerous places in <application>vacuumdb</> and other client programs
|

could become confused by database and role names containing double
|

quotes or backslashes. Tighten up quoting rules to make that safe.
|

Also, ensure that when a conninfo string is used as a database name
|

parameter to these programs, it is correctly treated as such throughout.

Introduce a new <option>-reuse-previous</> option

in <application>psql</>'s <command>\connect</> command to allow

explicit control of whether to re-use connection parameters from a

previous connection. (Without this, the choice is based on whether
|
||||
the database name looks like a conninfo string, as before.) This
|

allows secure handling of database names containing special

characters in <application>pg_dumpall</> scripts.

|

|

<para>
|

<application>pg_dumpall</> now refuses to deal with database and role
|

names containing carriage returns or newlines, as it seems impractical
|

to quote those characters safely on Windows. In future we may reject
|
||||
such names on the server side, but that step has not been taken yet.

These are considered security fixes because crafted object names
|

containing special characters could have been used to execute

executes <application>pg_dumpall</> or other routine maintenance
|

operations. (CVE-2016-5424)

In several cases the <function>to_number()</> function would read one
