connection properties parsing provocates crash in 8.3.x! (TypeError [ERR_INVALID_ARG_TYPE])

[Apollon77]

We see a crash that happens in pg 8.3.x without changing anything. I was able to dig it down to 8.2.2 working fine 8.3.0 breaks.

TypeError [ERR_INVALID_ARG_TYPE]: The "string" argument must be one of type string, Buffer, or ArrayBuffer. Received type object

This also happens in Travis/Appveyor.
Connection properties are:
{"server":"localhost","host":"localhost","user":"postgres","password":"Password12!","max_idle":2,"max_active":100,"max_wait":10000,"when_exhausted":"block","options":{"encrypt":false}}

PS: Could it be that the "options" objects is now parsed/handled differently then before?

[charmander]

options was added as an option in #2216 (pg@8.3.0). There’s always the danger when passing unrecognized options that they’ll be added in the future, so it’s something to look out for with new minor versions.

Ok, thx, I remove it
