Functions

func AreSupportedPromscaleExtensionVersionsAvailable

func AreSupportedPromscaleExtensionVersionsAvailable(conn *pgx.Conn, extOptions ExtensionMigrateOptions) (bool, error)

func CheckExtensionsVersion

func CheckExtensionsVersion(conn *pgx.Conn, migrationFailedDueToLockError bool, extOptions ExtensionMigrateOptions) error

CheckExtensionsVersion checks for the correct version and enables the extension if it is at the right version

func CheckPromscaleVersion

func CheckPromscaleVersion(conn *pgx.Conn) error

func CheckVersions

func CheckVersions(conn *pgx.Conn, migrationFailedDueToLockError bool, extOptions ExtensionMigrateOptions) error

CheckVersions is responsible for verifying the version compatibility of installed Postgresql database and extensions.

func FetchInstalledExtensionVersion

func FetchInstalledExtensionVersion(conn *pgx.Conn, extensionName string) (semver.Version, bool, error)

func InstallUpgradePromscaleExtensions

func InstallUpgradePromscaleExtensions(db *pgx.Conn, extOptions ExtensionMigrateOptions) error

func InstallUpgradeTimescaleDBExtensions

func InstallUpgradeTimescaleDBExtensions(connstr string, extOptions ExtensionMigrateOptions) error

InstallUpgradeTimescaleDBExtensions installs or updates TimescaleDB Note that after this call any previous connections can break so this has to be called ahead of opening connections.

Also this takes a connection string not a connection because for updates the ALTER has to be the first command on the connection thus we cannot reuse existing connections

func MigrateExtension

func MigrateExtension(conn *pgx.Conn, extName string, extSchemaName string, validRange semver.Range, rangeString string, extOptions ExtensionMigrateOptions) error

Types

type ExtensionMigrateOptions
