@alexmatveev You need to use the latest git master or the latest git tag for it. 0.9 is antient.

[AlexanderMatveev]

@agentzh Would you please create an installation docs?

[agentzh]

@alexmatveev The simplest way is to use the OpenResty bundle which has the latest version of this ngx_postgres module by default: https://openresty.org.
