It seems to me that you would pass down just a string which gets
allocated for "options", and injection risks are something to be careful
about. Another possibility would be an array with comma-separated
arguments, say:
options = 'option1=foo,option2=bar'
There is already some work done with comma-separated arguments for the
parameter "extensions", now that's more work.

Yep, it seems to me that you have that right.

options
Specifies command-line options to send to the server at connection
start. For example, setting this to -c geqo=off sets the session's
value of the geqo parameter to off. Spaces within this string are
considered to separate command-line arguments, unless escaped with a
backslash (\); write \\ to represent a literal backslash. For a
detailed discussion of the available options, consult Chapter 19.
