Anda harus memiliki salah satu peran IAM ini di Google Cloud project yang Anda gunakan:
roles/alloydb.admin (peran IAM bawaan Admin AlloyDB)
roles/owner (peran IAM dasar Pemilik)
roles/editor (peran IAM dasar Editor)
Jika Anda tidak memiliki salah satu peran ini, hubungi Administrator Organisasi Anda untuk meminta
akses.
Mengaktifkan ekstensi
Secara umum, Anda mengaktifkan ekstensi dengan terhubung ke database di
instance utama cluster AlloyDB dan memasukkan perintah LOAD atau
CREATE EXTENSION.
Namun, beberapa ekstensi mengharuskan Anda menetapkan satu atau beberapa flag database
sebelum dapat menggunakan perintah LOAD atau CREATE EXTENSION untuk mengaktifkan
ekstensi. Anda menetapkan flag ini pada instance AlloyDB tempat Anda
ingin menggunakan ekstensi, baik instance tersebut adalah instance utama atau instance
kumpulan baca.
Prosedur
Jika diperlukan,
tetapkan flag database yang sesuai pada instance tempat Anda
ingin menggunakan ekstensi, baik instance utama maupun instance kumpulan baca.
Daftar ekstensi yang didukung
menunjukkan ekstensi mana yang memerlukan langkah ini dan menyatakan flag database mana yang harus Anda
tetapkan.
Pada command prompt psql, hubungkan ke database yang mengaktifkan ekstensi dan hapus ekstensi:
\cDB_NAMEDROPEXTENSIONEXTENSION_NAME;
Ulangi langkah sebelumnya untuk terhubung ke database lain yang mengaktifkan ekstensi dan hapus ekstensi di setiap database tersebut.
Jika ekstensi mengharuskan tanda database ditetapkan pada instance
tempat ekstensi digunakan, hapus tanda dari setiap instance tempat ekstensi
digunakan dengan mengikuti petunjuk di
Mengonfigurasi tanda database
instance.
Daftar ekstensi yang didukung
menunjukkan ekstensi mana yang memerlukan penetapan flag database dan mengidentifikasi
flag mana.

You set these flags on the AlloyDB instance where you\nwant to use the extension, whether that instance is the primary instance or read\npool instance.\n\n### Procedure\n\n1. If required, [set the appropriate database flags](/alloydb/docs/instance-configure-database-flags) on the instance where you\n want to use the extension, either the primary instance or a read pool instance.\n\n The [list of supported extensions](/alloydb/docs/reference/extensions)\n shows which extensions require this step and states which database flags you\n must set.\n2. Connect a `psql` client to the cluster's primary instance, as\n described in [Connect a psql client to\n an instance](/alloydb/docs/connect-psql).\n\n | **Note:** You must connect to the primary instance even if you are enabling the extension on a read pool instance.\n3. At the `psql` command prompt, connect to the database and create the extension: \n\n ```sql\n \\c \u003cvar translate=\"no\"\u003e\u003cspan class=\"devsite-syntax-n\"\u003eDB_NAME\u003c/span\u003e\u003c/var\u003e\n CREATE EXTENSION IF NOT EXISTS \u003cvar translate=\"no\"\u003e\u003cspan class=\"devsite-syntax-n\"\u003eEXTENSION_NAME\u003c/span\u003e\u003c/var\u003e;\n ```\n | **Note:** To create the [auto_explain](https://www.postgresql.org/docs/16/auto-explain.html) extension, use the \\`LOAD\\` command.\n4. If desired, repeat the previous step to connect to other databases and create the extension in each of them.\n\nDisable an extension\n--------------------\n\nYou disable an extension by reversing the procedure used to enable it.\n\n1. Connect a `psql` client to the cluster's primary instance, as\n described in [Connect a psql client to\n an instance](/alloydb/docs/connect-psql).\n\n | **Note:** You must connect to the primary instance even if you are disabling an extension that is only being used on read pool instances.\n2. At the `psql` command prompt, connect to the database that has the extension enabled and drop the extension: \n\n ```sql\n \\c DB_NAME\n DROP EXTENSION EXTENSION_NAME;\n ```\n3. Repeat the previous step to connect to any other databases that have the extension enabled and drop the extension in each of them.\n4. If the extension required that database flags be set on the instances\n where it was used, remove the flags from each of the instances where it was\n used by following the instructions in\n [Configure an instance's\n database flags](/alloydb/docs/instance-configure-database-flags).\n\n The [list of supported extensions](/alloydb/docs/reference/extensions)\n shows which extensions require setting of database flags and identifies\n which flags."]]
