skuName

Specifies the SKU Name for this PostgreSQL Server. The name of the SKU, follows the tier + family + cores pattern (e.g. B_Gen4_1, GP_Gen5_8). For more information see the product documentation. Possible values are B_Gen4_1, B_Gen4_2, B_Gen5_1, B_Gen5_2, GP_Gen4_2, GP_Gen4_4, GP_Gen4_8, GP_Gen4_16, GP_Gen4_32, GP_Gen5_2, GP_Gen5_4, GP_Gen5_8, GP_Gen5_16, GP_Gen5_32, GP_Gen5_64, MO_Gen5_2, MO_Gen5_4, MO_Gen5_8, MO_Gen5_16 and MO_Gen5_32.

Note: When replication is set up and sku_name is changed to a higher tier or more capacity for the primary, all replicas are scaled up to the same tier/capacity. This is an Azure requirement, for more information see the replica scaling documentation
