Encoder panics on composite type arrays containing pgtype.Numeric

[kirk-anchor]

Using an array of a composite type with a numeric column and no --go-type override results in a panic

panic: encode []FeeConfig: cannot convert {1 -2 2 false none} to Numeric

This does not occur if your generated structs use a string with --go-type 'numeric=string'

However pgtype.Numeric has a bug in string conversion, I reported it upstream jackc/pgtype#210

For now, I will use the last pggen commit that still contains QuerierConfig and everything works properly with --go-type 'numeric=github.com/shopspring/decimal.Decimal'

The string conversion bug has now been fixed in pgtype.Numeric so --go-type 'numeric=string' can be used as a workaround to allow using numeric columns in composite types
