Subject: Updated the blob regression test to actually use the getBlob/getClob methods
X-Git-Tag: REL7_4_BETA2~66
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=dcfa89537a7d3fbd5117748c266ff86cd8cfb880;p=postgresql

Updated the blob regression test to actually use the getBlob/getClob methods
and test them, in addition to testing the underlying LargeObject API methods.
