Staring at the code side by side; it might be the 3rd parameter to get_sql_params:
Compare: https://github.com/mbalmer/luapgsql/blob/9ce83ea9ee1502a377125fba96cc03466f5044ba/luapgsql.c#L439 vs https://github.com/mbalmer/luapgsql/blob/9ce83ea9ee1502a377125fba96cc03466f5044ba/luapgsql.c#L734

It also appears that the NULL check at https://github.com/mbalmer/luapgsql/blob/9ce83ea9ee1502a377125fba96cc03466f5044ba/luapgsql.c#L744 should be removed?

Can you recheck now that I fixed a blocking issue?

[mbalmer]

The NULL check is there in case calloc fauils (OOM)

Yes, I figured the lack of it in conn_execParams meant it was not required.
Actually it seems that it's missing in conn_execParams.

In any case, d592d3f fixes the main issue reported here. Thanks @geoffleyland

Yes, I figured the lack of it in |conn_execParams| meant it was not
required.
Actually it seems that it's /missing/ in |conn_execParams|.
