Hi,
I'd like to ask how to handle null values when fetching arrays into
ecpg. Always I get this error:
Data read from backend is not an array in line ...
I'm using indicators and I use char * variables for array values (for
all column types: int[], text[], bytea[]). It works when the value of
array is not null but when it's null I get the error above.
Can null values in columns of array type be handled in more convenient
way than using coalesce/nullif and special reserved value?
Thanks, Kuba
