paleolimbot opened a new issue, #1483:
URL: https://github.com/apache/arrow-adbc/issues/1483
It looks like the postgres enum type is not quite supported yet, although
there is a workaround:
``` r
library(adbcdrivermanager)
db <- adbc_database_init(
adbcpostgresql::adbcpostgresql(),
uri =
"postgresql://localhost:5432/postgres?user=postgres&password=password")
db |>
execute_adbc("CREATE TYPE mood AS ENUM ('sad', 'ok', 'happy')")
db |>
adbc_database_release()
# Have to recreate the database after because that's where we cache the types
con <- db <- adbc_database_init(
adbcpostgresql::adbcpostgresql(),
uri =
"postgresql://localhost:5432/postgres?user=postgres&password=password"
) |>
adbc_connection_init()
con |>
execute_adbc("CREATE TABLE x (a mood)") |>
execute_adbc("INSERT INTO x VALUES ('sad')") |>
execute_adbc("INSERT INTO x VALUES ('ok')")
# Currently returned as binary (i.e., COPY output)
con |>
read_adbc("SELECT * from x") |>
as.data.frame() |>
dplyr::pull(a) |>
unclass() |>
vapply(rawToChar, character(1))
#> [1] "sad" "ok"
```
