[nagios-plugins] check_pgsql is too restrictive with database names (#1214)

[Dan Langille]

Hi,

check_pgsql restricts database names to [^_a-zA-Z0-9-]

However, that's not valid for quoted identifiers, such as "freshports.org"

Any character, except null, is valid.

ref: http://www.postgresql.org/docs/current/interactive/sql-syntax-lexical.html#SQL-SYNTAX-IDENTIFIERS

"Quoted identifiers can contain any character, except the character with code zero."
