consolidate with cluster.GetPgbackrestEnvVars.

GetPodAntiAffinity returns the populated pod anti-affinity json that should be attached to the various pods comprising the pg cluster.

GetPodAntiAffinityType returns the type of pod anti-affinity to use.

GetPodSecurityContext will generate the security context required for a Deployment by incorporating the standard fsGroup for the user that runs the container (typically the "postgres" user), and adds any supplemental groups that may need to be added, e.g.

GetRepoType returns the proper repo type to set in container based on the backrest storage type provided If there are multiple types, the default returned is "posix".

GetResourcesJSON is a pseudo-legacy method that creates JSON that applies the CPU and Memory settings.

GetS3VerifyTLSSetting parses the configured value as a boolean to ensure a valid option is used, then returns the pgBackRest S3 configuration value to either enable or disable TLS verification as the expected string value.

GetSyncReplication returns true if synchronous replication has been enabled using either the pgcluster CR specification or the pgo.yaml configuration file.

GetTablespaceNamePVCMap returns a map of the tablespace name to the PVC name.

GetTablespaceNames generates a comma-separated list of the format "tablespaceName1,tablespceName2" so that the PVC containing a tablespace can be properly mounted in the container, and the tablespace can be referenced by the specified human readable name.

GetTablespacePVCName returns the formatted name that is used for a PVC for a tablespace.

GetTablespaceStorageTypeMap returns a map of "tablespaceName => storageType".

GetTablespaceVolumeMountsJSON Creates an appendable list for the volumeMounts that are used to mount table spacs and returns them in a JSON-ish string.

GetTableSpaceVolumeName returns the name that is used to identify the volume that is used to mount the tablespace.

GetTablespaceVolumes Creates an appendable list for the volumes section of a Kubernetes pod.

IsLocalAndGCSStorage a boolean indicating whether or not local and gcs storage should be enabled for pgBackRest based on the backrestStorageType string provided.

IsLocalAndS3Storage a boolean indicating whether or not local and s3 storage should be enabled for pgBackRest based on the backrestStorageType string provided.

NamespaceOperatingMode returns the namespace operating mode for the current Operator installation, which is stored in the "namespaceOperatingMode" variable.

OverrideClusterContainerImages is a helper function that provides the appropriate hooks to override any of the container images that might be deployed with a PostgreSQL cluster.

RemovePrimaryOnRoleChangeTag sets the 'primary_on_role_change' tag to null in the Patroni DCS, effectively removing the tag.

ScaleDeployment scales a deployment to a specified number of replicas.

SetContainerImageOverride determines if there is an override available for a container image, and sets said value on the Kubernetes Container image definition.

SetupNamespaces is responsible for the initial namespace configuration for the Operator install.

Switchover performs a controlled switchover within a PostgreSQL cluster, i.e.

UpdatePGHAConfigInitFlag sets the value for the "init" setting in the PGHA configMap for the PG cluster to the value specified via the "initVal" parameter.

PGHAConfigInitSetting determines whether or not initialization logic should be run in the crunchy-postgres-ha (or GIS equivilaent) container.

PGHAConfigMapSuffix defines the suffix for the name of the PGHA configMap created for each PG cluster.

PGHAConfigReplicaBootstrapRepoType defines an override for the type of repo (local, S3, etc.) that should be utilized when bootstrapping a replica (i.e.
