Using `strlcpy` to copy variables holding PostgreSQL names can cause issues since names are fixed-size types of length 64. This means that any data that follows the initial null-terminated string will also be part of the data. Instead of using `const char*` for PostgreSQL names, use `NameData` type for PostgreSQL names and use `namestrcpy` to copy them rather than `strlcpy`.
