fix for no match of right hand side value undefined default

[221V]

hello :)

there are next description in readme:

pooler_max_queue -- pool queue length. It there are more clients waiting for worker from pool then epgsql_pool:query returns {error, pool_overload}. 100 clients by default.

epgsql_pool/src/epgsql_pool.erl

Line 41 in f5e492f

{ok, MaxQueue} = application:get_env(epgsql_pool, pooler_max_queue),

and we can see this line in code

I have no idea why I got error here yesterday --
with the same configs that I got no errors for years before with the same deps..

no match of right hand side value undefined

but I fix this error by editing this line of code:

- {ok, MaxQueue} = application:get_env(epgsql_pool, pooler_max_queue),
+ MaxQueue = application:get_env(epgsql_pool, pooler_max_queue, 100),

just FYI

thank you for your contribution to open source :)
happy holidays to you :)
